DESCRIPTION

4-bit binary counters feature an internal carry look-ahead and can be used for high-speed counting. Synchronous operation is provided by having all flip-flops clocked simultaneously on the positive-going edge of the clock. The clock input is buffered.

FEATURES

• Synchronous counting and loading

• Two count enable inputs for n-bit cascading

• Positive edge-triggered clock

• Asynchronous Master Reset (74F161A)

• Synchronous Reset (74F163A)

• High speed synchronous expansion

• Typical count rate of 130MHz

• Industrial range (–40°C to +85°C) available
