TECHNICAL DATA
KK74HC4094A
8-Bit Serial-Input Shift Register
With Latched 3-State Outputs
High-Performance Silicon-Gate CMOS
The KK74HC4094A 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 SQ_H can be used to cascade several devices.
Data on the SQ_H output is transferred to a second output (SQ_H’) 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
