74LS196, 4-STAGE PRESETTABLE RIPPLE COUNTERS
The LS196 and LS197 are asynchronously presettable decade and binary ripple counters.
The LS196 Decade Counter is partitioned into divide-by-two and divide-by-five sections while the LS197 is partitioned into divide-by-two and divideby-eight sections, with all sections having a separate Clock input.
4-STAGE PRESETTABLE RIPPLE COUNTERS The SN54/74LS196 decade counter is partitioned into divide-by-two and divide-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 dissipation of only 80 mW.
