The ’F161A and ’F163A are high-speed synchronous modu- lo-16 binary counters� They are synchronously presettable for application in programmable dividers and have two types of Count Enable inputs plus a Terminal Count output for versatility in forming synchronous multi-stage counters� The ’F161A has an asynchronous Master-Reset input that over- rides all other inputs and forces the outputs LOW� The ’F163A has a Synchronous Reset input that overrides counting and parallel loading and allows the outputs to be simultaneously reset on the rising edge of the clock� The ’F161A and ’F163A are high-speed versions of the ’F161 and ’F163�
The 54F/74F161A and 54F/74F163A are high-speed synchronous modulo-16 binary counters designed for use in programmable dividers and multi-stage counter applications. The 54F/74F161A features an asynchronous Master-Reset input, while the 54F/74F163A features a synchronous Reset input. Both devices offer two types of Count Enable inputs plus a Terminal Count output for versatility in forming synchronous multi-stage counters.
