54F161ADC中文资料Synchronous Presettable Binary Counter数据手册TI规格书

描述 Description

General Description
The ’F161A and ’F163A are 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 ’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.
