MIC50398/50399 Micrel MIC50398/MIC50399 Six Decade Counter / Display Decoder Not Remended 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. 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. - 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...
