Overview
MIC50398/50399 Micrel MIC50398/MIC50399 Six Decade Counter / Display Decoder Not Recommended for New Designs 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.
Features • • • • • • • • Single power supply Schmitt-Trigger on the count-input Six decades of synchronous up/down counting Look-ahead carry or borrow Loadable counter Multiplexed seven-segment outputs MIC50398N Multiplexed BCD outputs, MIC50399N Internal scan oscillator Pin ...
