SNx4HC164 8-Bit Parallel-Out Serial Shift Registers
1 Features 3 Description
These 8-bit shift registers feature AND-gated serial

• Wide Operating Voltage Range of 2 V to 6 V
inputs and an asynchronous clear (CLR) input. The
• Outputs Can Drive Up to 10 LSTTL Loads
gated serial (A and B) inputs permit complete control
• Low Power Consumption, 80-μA Maximum I

over incoming data; a low at either input inhibits entry
of the new data and resets the first flip-flop to the low

level at the next clock (CLK) pulse. A high-level input
• ±4-mA Output Drive at 5 V
enables the other input, which then determines the
• Low Input Current of 1-μA Maximum
state of the first flip-flop. Data at the serial inputs can
be changed while CLK is high or low, provided the

minimum set-up time requirements are met. Clocking
