August 1998
General Description
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.
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.
