74LVX163

The 74LVX163 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 MR inputs are active on low logic levels. Presetting is synchronous to rising edge of the CLK and the Clear function of the LVX163 is synchronous to the CLK. Two enable inputs (CEP and CET) 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 of the 74LVX163 up to 7V allowing the interface of 5V systems to 3V systems.
