DESCRIPTION
The M54/74HCT165 is a high speed CMOS 8 BIT
PISO SHIFT REGISTER fabricated in silicon gate
C2MOS 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 entrens 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
gates.
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.This integrated
circuit has input and output characteristics that are
fully compatible with 54/74 LSTTL logic families.
M54/74HCT devices are designed to directly
interface HSCMOS systems with TTL and NMOS
components. They are also plug in replacements for
LSTTL devices giving a reduction of power
consumption. All inputs are equipped with
protection circuits against static discharge and
transient excess voltage.

(*) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.
(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC
