4-stage Presettable Ripple Counters , Inc

The SN54/74LS196 decade Counter is partitioned into divide-by-two and di- vide-by-five sections which CAN be combined to count either in BCD (8, 4, 2, 1) sequence or in a bi-quinary mode producing a 50% duty cycle output. The SN54/74LS197 contains divide-by-two and divide-by-eight sections which CAN be combined to form a modulo-16 binary Counter Low Power Schottky technology is used to achieve typical count rates of 70 MHz and power dis- sipation of only 80 mW. Both circuit types have a Master Reset (MR) input which overrides all other inputs and asynchronously forces all outputs LOW. A Parallel Load input (PL) overrides clocked operations and asynchronously loads the data on the Par- allel Data inputs (Pn) into the Flip-Flops This preset feature makes the circuits usable as programmable Counters The circuits CAN also be used as 4-bit Latches loading data from the Parallel Data inputs when PL is LOW and stor- ing the data when PL is HIGH.
