DESCRIPTION

The 74ACT161 is an advanced high-speed CMOS

SYNCRONOUS PRESETTABLE COUNTER

fabricated with sub-micron silicon gate and

double-layer metal wiring C

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

-O

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.
