Counter Single 4-Bit Sync Binary UP 16-Pin SOIC N Rail

The 74F161A is high-speed synchronous modulo-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 74F161A has an asynchronous Master-Reset input that overrides all other inputs and forces the outputs LOW. The 74F163A is high-speed versions of the 74F161 and 74F163.

• Synchronous counting and loading
• High-speed synchronous expansion
• Typical count frequency of 120MHz
