BCD DECADE COUNTERS/

4-BIT BINARY COUNTERS

The LS160A/161A/162A/163A are high-speed 4-bit synchronous count-

ers. They are edge-triggered, synchronously presettable, and cascadable

MSI building blocks for counting, memory addressing, frequency division and

other applications. The LS160A and LS162A count modulo 10 (BCD). The

LS161A and LS163A count modulo 16 (binary.)

BCD DECADE COUNTERS/

4-BIT BINARY COUNTERS

The LS160A and LS161A have an asynchronous Master Reset (Clear)

input that overrides, and is independent of, the clock and all other control

inputs.TheLS162AandLS163AhaveaSynchronousReset(Clear)inputthat

overrides all other control inputs, but is active only during the rising clock

edge.
