74LVX163M数据手册集成电路（IC）的计数器除法器规格书PDF

描述 Description

General Description
The LVX163 is a synchronous modulo-16 binary counter. This device is synchronously presettable for application in programmable dividers and has two types of Count Enable inputs plus a Terminal Count output for versatility in forming multistage counters. The CLK input is active on the rising edge. Both PE and CLR inputs are active on low logic levels. Presetting is synchronous to rising edge of CLK and the Clear function of the LVX163 is synchronous to CLK. Two enable inputs (ENP and ENT) and Carry Output are provided to enable easy cascading of counters, which facilitates easy implementation of n-bit counters without using external gates.
The inputs tolerate voltages up to 7V allowing the interface of 5V systems to 3V systems.
