CD74HC4518 - Dual Synchronous Counters

General Description

The CD74HC4518 is a dual BCD up-counter.

The ’HC4520 and CD74HCT4520 are dual binary up-counters.

Each device consists of two independent internally synchronous 4-stage counters.

Key Features

  • Positive or Negative Edge Triggering.
  • Synchronous Internal Carry Propagation.
  • Fanout (Over Temperature Range) - Standard Outputs.
  • 10 LSTTL Loads - Bus Driver Outputs.
  • . . . 15 LSTTL Loads.
  • Wide Operating Temperature Range . . . -55oC to 125oC.
  • Balanced Propagation Delay and Transition Times.
  • Significant Power Reduction Compared to LSTTL Logic ICs.
  • HC Types - 2V to 6V Operation - High Noise I.
