74HC(T)6323A: Programmable ripple counter with oscillator; 3-state
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 and sets
the output buffer in the 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
VCC.
