DESCRIPTION
The 74AHC/AHCT164 shift registers are high-speed
silicon-gate CMOS devices and are pin compatible with
Low power Schottky TTL (LSTTL). They are specified in
compliance with JEDEC standard No. 7A.
The 74AHC/AHCT164 input signals are 8-bit serial
through one of two inputs (D
sa
or D
sb
); either input can be
used as an active HIGH enable for data entry through the
other input. Both inputs must be connected together or an
unused input must be tied HIGH.
Data shifts one place to the right on each LOW-to-HIGH
transition of the clock (CP) input and enters into Q
0
, which
is a logical AND of the two data inputs (D
sa
, D
sb
) that
existed one set-up time prior to the rising clock edge.
A LOW level on the master reset (MR) input overrides all
other inputs and clears the register asynchronously,
forcing all outputs LOW.
