CD74HC163 - High-Speed CMOS Logic Presettable Counters

Download the CD74HC163 datasheet PDF. This datasheet also covers the CD74HC161 variant, as both devices belong to the same high-speed cmos logic presettable counters family and are provided as variant models within a single manufacturer datasheet.

Description

Two count enables, PE and TE, in each counter are provided for n-bit cascading.

In all counters reset action occurs regardless of the level of the SPE, PE and TE inputs (and the clock input, CP, in the ’HC161 and ’HCT161 types).

Features

  • ’HC161, ’HCT161 4-Bit Binary Counter, Asynchronous Reset.
  • ’HC163, ’HCT163 4-Bit Binary Counter, Synchronous Reset.
  • Synchronous Counting and Loading.
  • Two Count Enable Inputs for n-Bit Cascading.
  • Look-Ahead Carry for High-Speed Counting.
  • Fanout (Over Temperature Range) - Standard Outputs.
  • 10 LSTTL Loads - Bus Driver Outputs.
  • . . . 15 LSTTL Loads.
  • Wide Operating Temperature Range . . . -55oC t.
