Additional preview pages of the DM74S161 datasheet.

These synchronous, presettable counters feature an internal carry look-ahead for application in high-speed counting designs.

They are 4-bit binary counters.

The carry output is decoded by means of a NOR gate, thus preventing spikes during the normal counting mode of operation.
