Six Decade Counter / Display Decoder

Not Recommended for New Designs

General Description

Features

The MIC50395 is an ion-implanted, P-channel MOS six-

decade synchronous up/down-counter/display driver with

compare-register and storage-latches. The counter as well

as the register can be loaded digit-by-digit with BCD data.

The counter has an asynchronous-clear function.

Loadable counter

Scanning is controlled by the scan oscillator input which is

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

six-decade register is constantly compared to the state of

the six-decade counter and when both the register and the

counter have the same content, an EQUAL signal is gener-

ated. The contents of the counter can be transferred into the

6-digit latch which is then multiplexed from MSD to LSD in

BCD and 7-segment format to the output. The seven-

segment decoder incorporates a leading-zero blanking

circuit which can be disabled by an external signal. This

device is intended to interface directly with the standard

CMOS logic families.

Ordering Information

The MIC50396 and MIC50397 operate identically to the

MIC50395 except that two digits in each were reprogrammed

to provide divide by six circuitry instead of divide by ten. The

MIC50396 is well suited for industrial timer applications while

the MIC50397 is best suited for stop watch or real time

computer clock applications.
