It has the same high speed performance of LSTTL combined with true COMS low power consumption.
This counter circuit contains independent ripple carry counters and two 4-bit ripple carry binary counters, which can be cascated to create a single divide by 256 counter.
Each 4-bit counter is incremented on the high to low transition (nega...
