DESCRIPTION
The 74ACT161 is an advanced high-speed CMOS
SYNCRONOUS PRESETTABLE COUNTER
fabricated with sub-micron silicon gate and
double-layer metal wiring C
2
MOS tecnology. It is a
4 bit binary counter with Asynchronous Clear.
The circuit have four fundamental modes of
operation, in order of preference: synchronous
reset, parallel load, count-up and hold. Four
control inputs, (CLEAR), (LOAD), (PE) and (TE),
determine the mode of operation as shown in the
Truth Table. A LOW signal on CLEAR overrides
counting and parallel loading and sets all outputs
on LOW state. A LOW signal on LOAD overrides
PIN CONNECTION AND IEC LOGIC SYMBOLS
counting and allows information on Parallel Data
inputs to be loaded into the flip-flop on the next
rising edge of CLOCK. With LOAD and CLEAR
HIGH, PE and TE permit counting when both are
HIGH. Conversely, a LOW signal on either PE and
TE inhibits counting.
The CARRY OUTPUT is HIGH when TE is HIGH
and counter is in state 15.
The device is designed to interface directly High
Speed CMOS systems with TTL, NMOS and
CMOS output voltage levels.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
