TECHNICAL DATA

IN74HC4094A

8-Bit Serial-Input Shift Register

With Latched 3-State Outputs

High-Performance Silicon-Gate CMOS

The IN74HC4094A is identical in pinout to the LS/ALS4094. The

device inputs are compatible with standard CMOS outputs; with pullup

resistors, they are compatible with LS/ALSTTL outputs.

This device consists of an 8-bit shift register and 8-bit D-type latch

with three-state parallel outputs. Data is shifted serially through the shift

register on the positive going transition of the clock input signal. The

output of the last stage SQH can be used to cascade several devices.

Data on the SQH output is transferred to a second output (SQH’) on the

following negative transition of the clock input signal. The data of each

stage of the shift register is provided with a latch, which latches data on

the negative going transition of the Strobe input signal. When the Strobe

input is held high, data propagates through the latch to a 3-state output

buffer.

This buffer is enabled when Output Enable input is taken high.

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 2.0 to 6.0 V

• Low Input Current: 1.0 μA

• High Noise Immunity Characteristic of CMOS Devices
