MC74HC163A - Presettable Counters

Download the MC74HC163A datasheet PDF. This datasheet also covers the MC74HC161A variant, as both devices belong to the same presettable counters family and are provided as variant models within a single manufacturer datasheet.

General Description

The HCT161A/163A are programmable 4 bit synchronous counters that feature parallel Load, synchronous or asynchronous Reset, a Carry Output for cascading and count

enable controls.

The HCT161A and HCT163A are binary counters with asynchronous Reset and synchronous Reset, respectively.

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Presettable Counters MC54/74HCT161A MC54/74HCT163A High–Performance Silicon–Gate CMOS The MC54/74HCT161A and HCT163A are identical in pinout to the LS161A and LS163A. These devices may be used as level converters for interfacing TTL or NMOS outputs to high speed CMOS inputs. The HCT161A and HCT163A are programmable 4–bit binary counters with asynchronous and synchronous reset, respectively. 16 1 J SUFFIX CERAMIC PACKAGE CASE 620–10 • • • • • • • Output Drive Capability: 10 LSTTL Loads TTL, NMOS Compatible Input Levels Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 4.5 to 5.
