?Members of the Texas Instruments Widebus ?Family

State-of-the-Art Advanced BiCMOS Technology (ABT)Design for 3.3-V Operation and Low Static-Power Dissipation

Support Mixed-Mode Signal Operation (5-V Input and Output Voltages With 3.3-V V CC )

?Support Unregulated Battery Operation Down to 2.7V

?Typical V OLP (Output Ground Bounce)<0.8V at V CC =3.3V,T A =25°C

?I off and Power-Up 3-State Support Hot Insertion

?Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors ?Latch-Up Performance Exceeds 500mA Per JESD 17

ESD Protection Exceeds JESD 22

–2000-V Human-Body Model (A114-A)–200-V Machine Model (A115-A)

The 'LVTH16244A devices are 16-bit buffers and line drivers designed for low-voltage (3.3-V)V CC operation,but with the capability to provide a TTL interface to a 5-V system environment.These devices can be used as four 4-bit buffers,two 8-bit buffers,or one 16-bit buffer.These devices provide true outputs and symmetrical active-low output-enable (OE)inputs.

Active bus-hold circuitry holds unused or undriven inputs at a valid logic https://www.wendangku.net/doc/155141433.html,e of pullup or pulldown resistors with the bus-hold circuitry is not recommended.

When V CC is between 0and 1.5V,the devices are in the high-impedance state during power up or power down.However,to ensure the high-impedance state above 1.5V,OE should be tied to V CC through a pullup resistor;the minimum value of the resistor is determined by the current-sinking capability of the driver.

These devices are fully specified for hot-insertion applications using I off and power-up 3-state.The I off circuitry disables the outputs,preventing damaging current backflow through the devices when they are powered down.The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down,which prevents driver conflict.

Please be aware that an important notice concerning availability,standard warranty,and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
