MC74AC160D

Manufacturer Part Number
MC74AC160D
Description
Synchronous presettable BCD decade counter
Manufacturer
Motorola
Datasheet
Synchronous Presettable
BCD Decade Counter
synchronous decade counters operating in the BCD (8421) sequence. They
are synchronously presettable for application in programmable dividers and have
two types of Count Enable inputs plus a Terminal Count output for versatility in
forming synchronous multistage counters. The MC74AC160/74ACT160 has an
asynchronous Master Reset input that overrides all other inputs and forces the
outputs LOW. The MC74AC162/74ACT162 has a Synchronous Reset input that
overrides counting and parallel loading and allows all outputs to be simultaneously
reset on the rising edge of the clock.
