74HCT6323AD - Programmable ripple counter

Download the 74HCT6323AD datasheet PDF. This datasheet also covers the 74HC6323A variant, as both devices belong to the same programmable ripple counter family and are provided as variant models within a single manufacturer datasheet.

General Description

The 74HC6323A; 74HCT6323A is an oscillator 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.

Key Features

  • Programmable 3-stage ripple counter.
  • Suitable for over-tone crystal.

74HC6323A; 74HCT6323A Programmable ripple counter with oscillator; 3-state Rev. 4 — 9 July 2018 Product data sheet 1 General description The 74HC6323A; 74HCT6323A is an oscillator 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.
