DESCRIPTION

The M54/74HC165 is a high speed CMOS 8 BIT

PISO SHIFT REGISTER fabricated in silicon gate

MOS technology. It has the same high speed

performance of LSTTL combined with true CMOS

low power consumption.

It achives the high speed operation similar to

equivalent LSTTL while maintaining the CMOS low

power dissipation.

This device contains eight clocked master slave RS

flip-flops connected as a shift register, with auxiliary

gating to provide over-riding asynchronous parallel

entry. Parallel data entres when the shift/load input

is low. The parallel data can change while shift/load

is low, provided that the recommended set-up and

hold times are observed. For clocked operation,

shift/load must be high. The two clock input perform

identically; one can be used as a clock inhibit by

applying a high signal; to permit this operation

clocking is accomplished through a 2 input nor gate.

To avoid double clocking, however, the inhibit signal

should only go high while the clock is high.

Otherwise the rising inhibit signal will cause the

same response as rising clock edge.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
