General Description

The MAX3013–MAX3022 8-channel level translators pro-vide the level shifting necessary to allow 100Mbps data transfer in a multivoltage system. Externally applied volt-ages, V CC and V L , set the logic levels on either side of the device. Logic signals present on the V L side of the device appear as a higher voltage logic signal on the V CC side of the device, and vice-versa.

The MAX3013–MAX3022 feature an EN input that, when at logic low, places all inputs/outputs on both sides in tristate and reduces the V CC and V L supply currents to 0.1μA. These devices operate at a guaranteed data rate of 100Mbps for V L > 1.8V.

The MAX3013–MAX3022 accept a V CC voltage from +1.65V to +3.6V and a V L voltage from +1.2V to (V CC -0.4V), making them ideal for data transfer between low-voltage ASICs/PLDs and higher voltage systems. The MAX3013–MAX3022 are available in 5 x 4 UCSP?, 20-pin 5mm x 5mm QFN, and 20-pin TSSOP packages.

Detailed Description

The MAX3013–MAX3022 logic-level translators provide the level shifting necessary to allow 100Mbps data trans-fer in a multivoltage system. Externally applied voltages,V CC and V L , set the logic levels on either side of the device. Logic signals present on the V L side of the device appear as a higher voltage logic signal on the V CC side of the device, and vice-versa. The MAX3013bidirectional level translator allows data translation in either direction (V L ?V CC ) on any single data line. The MAX3014–MAX3022 unidirectional translators level-shift data in one direction (V L →V CC or V CC →V L ) on any single data line. The MAX3013–MAX3022 accept V L from +1.2V to (V CC - 0.4V) and operate with V CC from +1.65V to +3.6V, making them ideal for data transfer between low-voltage ASICs/PLDs and higher voltage systems.The MAX3013–MAX3022 feature an input enable mode (EN) that reduces V CC and V L supply currents to 0.1μA,when in tristate mode. These devices operate at a guaranteed data rate of 100Mbps for V L > +1.8V.

Level Translation

For proper operation, ensure that +1.65V ≤V CC ≤+3.6V,+1.2V ≤V L ≤(V CC - 0.4V). During power-up sequencing,V L ≥V CC does not damage the device. During power-supply sequencing, when V CC is floating and V L is pow-ering up, up to 40mA current can be sourced to each load on the V L side, yet the device does not latch up.The maximum data rate depends heavily on the load capacitance (see the Typical Operating Characteristics ,Rise/Fall Times), output impedance of the driver, and the operating voltage range (see the Timing Characteristics ).

Input Driver Requirements

The MAX3013–MAX3022 architecture is based on a one-shot accelerator output stage (see Figure 5).Accelerator output stages are always in tristate mode except when there is a transition on any of the transla-tors on the input side, either I/O V L or I/O V CC . Then, a short pulse is generated during which the accelerator output stages become active and charge/discharge the capacitances at the I/Os. Due to its bidirectional nature,both input stages become active during the one-shot pulse. This can lead to some current feeding into the external source that is driving the translator. However,this behavior helps to speed up the transition on the driven side.

For proper operation, the external driver must meet the following conditions: <25?output impedance and >20mA output current. Figure 6shows a graph of Typical Input Current vs. Input Voltage.

Output Load Requirements

The MAX3013–MAX3022 I/O were designed to drive CMOS inputs. Do not load the I/O lines with a resistive load less than 25k ?. Also, do not place an RC circuit at the input of the MAX3013–MAX3022 to slow down the edges. If a slower data rate is required, please see the MAX3000E/MAX3001E logic-level translator.

For I 2C? level translation, please refer to the MAX3372E–MAX3379E/MAX3390E–MAX3393E data sheet.

Enable Input (EN)

The MAX3013–MAX3022 feature an EN input. Pull EN low to set the MAX3013–MAX3022’s I/O on both sides in tristate output mode. Drive EN to logic high (V L ) for normal operation.

Applications Information

Power-Supply Decoupling

To reduce ripple and the chance of introducing data errors, bypass V L and V CC to ground with a 0.1μF ceramic capacitor. Place the bypass capacitors as close to the power-supply input pins as possible.

8-Bit Bus Translation

The MAX3013–MAX3022 level-shift the data present on the I/O line between +1.2V to +3.6V, making them ideal for level translation between a low-voltage ASIC and a higher voltage system. The Typical Operating Circuit shows the MAX3013 bidirectional translator in an 8-bit bus level translation from a 1.8V system to a 3.3V sys-tem and vice versa.

Unidirectional vs. Bidirectional Level

Translator

The MAX3013 bidirectional translator can operate as a unidirectional device to translate signals without inver-sion. The MAX3014–MAX3022 unidirectional translators level-shift data in one direction (V L →V CC or V CC →V L )on any single data line (see the Ordering Information ).These devices provide the smallest solution (UCSP pack-age) for unidirectional level translation without inversion.
