MM54HC192 MM74HC192 Synchronous Decade Up Down Counters MM54HC193 MM74HC193 Synchronous Binary Up Down Counters January 1988 MM54HC192 MM74HC192 Synchronous Decade Up Down Counters MM54HC193 MM74HC193 Synchronous Binary Up Down Counters General Description These high speed synchronous counters utilize advanced silicon-gate CMOS technology to achieve the high noise immunity and low power consumption of CMOS technology along with the speeds of low power Schottky TTL The MM54HC192 MM74HC192 is a decade counter and the MM54HC193 MM74HC193 is a binary counter Both counters have two separate clock inputs an UP COUNT input and a DOWN COUNT input All outputs of the flip-flops are simultaneously triggered on the low to high transition of either clock while the other input is held high The direction of counting is determined by which input is clocked These counters may be preset by entering the desired data on the DATA A DATA B DATA C and DATA D inputs When the LOAD input is taken low the data is loaded independently of either clock input This feature allows the counters to be used as divide-by-n counters by modifying the count length with the preset inputs In addition both counters can also be cleared This is accomplished by inputting a high on the CLEAR input All 4 internal stages are set to a low level independently of either COUNT input Both a BORROW and CARRY output are provided to enable cascading of both up and down counting functions The BORROW output produces a negative going pulse when the counter underflows and the CARRY outputs a pulse when the counter overflows The counters can be cascaded by connecting the CARRY and BORROW outputs of one device to the COUNT UP and COUNT DOWN inputs respectively of the next device All inputs are protected from damage due to static discharge by diodes to VCC and ground Features Y Y Y Y Y Y Typical propagation delay Count up to Q 28 ns Typical operating frequency 27 MHz Wide power supply range 2 – 6V Low
