Six Decade Counter / Display Decoder

Not Recommended for New Designs

General Description

Features

The MIC50398/9 is an ion-implanted, P-channel MOS

six-decade synchronous up/down-counter/display driver

with storage latches. The counter can be loaded

digit-by-digit with BCD data. The counter has an

asynchronous-clear function.

Internal scan oscillator

Scanning is controlled by the scan oscillator input which is

self-oscillating or can be driven by an external signal. The

contents of the counter can be transferred into the 6-digit

latch which is then multiplexed from MSD to LSD in BCD or

7-segment format to the output. These devices are intended

to interface directly with the standard CMOS logic families.
