74VHC164
8-Bit Serial-In, Parallel-Out Shift Register
General Description
The VHC164 is an advanced high-speed CMOS device
fabricated with silicon gate CMOS technology. It achieves
the high-speed operation similar to equivalent Bipolar
Schottky TTL while maintaining the CMOS low power dissi-
pation. The VHC164 is a high-speed 8-Bit Serial-In/Paral-
lel-Out Shift Register. Serial data is entered through a 2-
input AND gate synchronous with the LOW-to-HIGH transi-
tion of the clock. The device features an asynchronous
Master Reset which clears the register, setting all outputs
LOW independent of the clock. An input protection circuit
insures that 0V to 7V can be applied to the input pins with-
out regard to the supply voltage. This device can be used
to interface 5V to 3V systems and two supply systems such
as battery backup. This circuit prevents device destruction
due to mismatched supply and input voltages.
Features
