Low Voltage Synchronous Binary Counter with
Synchronous Clear
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 MR inputs are active on low logic lev-
els. 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
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

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.
