GENERAL DESCRIPTION
The HC/HCT6323A are high-speed
Si-gate CMOS devices.
They are specified in compliance with
JEDEC standard no. 7A.
The HC/HCT6323A are oscillators
designed for quartz crystal combined
with a programmable 3-state counter,
a 3-state output buffer and an
overriding asynchronous master
reset (MR). With the two select inputs
S1 and S2 the counter can be
switched in the divide-by-1, 2, 4 or 8
mode. If left floating the clock is
divided by 8. The oscillator is
designed to operate either in the
fundamental or third overtone mode
depending on the crystal and external
components applied. On-chip

capacitors minimize external
component count for third overtone
crystal applications.
The oscillator may be replaced by an
external clock signal at input X1. In
this event the other oscillator pin (X2)
must be floating. The counter
advances on the negative-going
transition of X1. A LOW level on MR
resets the counter, stops the oscillator

3-state condition. MR can be left
floating since an internal pull-up
resistor will make the MR inactive. In
the HCT version, the MR input and
the two mode select pins S1 and S2
are TTL compatible, but the X1 input
has CMOS input switching levels and
may be driven by a TTL output using
a pull-up resistor connected to V
