High–Performance Silicon–Gate CMOS
The MC74HC194 is identical in pinout to the LS194 and the MC14194B
metal gate CMOS device. The device inputs are compatible with standard
CMOS outputs; with pull–up resistors, they are compatible with LSTTL
outputs.
This static shift register features parallel load, serial load (shift right and
shift left), hold, and reset modes of operation. These modes are tabulated in
the Function Table, and further explanation can be found in the Pin
Description section.
Output Drive Capability: 10 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2 to 6 V
Low Input Current: 1
μ
A
High Noise Immunity Characteristic of CMOS Devices
In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
Chip Complexity 164 FETs or 41 Equivalent Gates

H = high level (steady state)
L = low level (steady state)
X = don’t care
= transition from low to high level.
a, b, c, d = the level of steady–state input at inputs A, B, C, or D, respectively.
QAn, QBn, QCn, QDn = the level of QA, QB, QC, or QD, respectively, before
the most recent
transition of the clock.
