synchronous 4-bit counter with asynchronous clear . synchronous 4-bit counter.
s Switching specifications at 50 pF s Switching specifications guaranteed over full temperature and VCC range s Advanced oxide-isolated, ion-implanted Schottky TTL proces.
These synchronous presettable counters feature an internal carry look ahead for application in high speed counting designs. The DM74AS161 and DM74AS163 are 4-bit binary counters. The DM74AS161 clear asynchronously, while the DM74AS163 clear synchrono.
