TECHNICAL DATA

KK 74LV164

8-BIT SERIAL-IN/PARALLEL-OUT SHIFT REGISTER

The KK function compatible with the KK 74HC/HCT164.

The KK data entry and an output from each of the eight stages. Data is entered serially through one of two inputs (DSA or DSB); either input can be used as an active HIGH enable for data entry through the other input. Both

inputs must be connected together or an unused input must be tied HIGH.

Data shifts one place to the right on each LOW-to-HIGH transition of

the clock (CP) input and enters into Q 0, which is the logical AND of the two data inputs (DSA, DSB ) that existed one set-up time prior to the rising clock edge. A LOW on the master reset (MR) input overrides all other inputs and clears the register asynchronously, forcing all outputs LOW.

? Outputs Directly Interface to CMOS, NMOS, and TTL ? Operating Voltage Range: 1.2 to 5.5 V

? Low Input Current: 1.0 μA, 0.1 μА at Т = 25 °С ? Output Current: 6 mA at V CC = 3.0 V; 12 mA at V CC = 4.5 V ? High Noise Immunity Characteristic of CMOS Devices

This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, V IN and V OUT should be constrained to the range GND≤(V IN or V OUT)≤V CC.

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V CC). Unused outputs must be left open.
