SN54/74LS196

SN54/74LS197

4-STAGE PRESETTABLE

RIPPLE COUNTERS

TheSN54/74LS196decadecounterispartitionedintodivide-by-twoanddi-

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.

4-STAGE PRESETTABLE

RIPPLE COUNTERS

LOW POWER SCHOTTKY

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 (P ) 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.

• Low Power Consumption — Typically 80 mW

• High Counting Rates — Typically 70 MHz

• Choice of Counting Modes — BCD, Bi-Quinary, Binary

• Asynchronous Presettable

• Asynchronous Master Reset

• Easy Multistage Cascading
