National Semiconductor 54F/74F161A 54F/74F163A handbook
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.
