APPLICATIONS Control counters Timers Frequency dividers Time-delay circuits CIO (Compact Integrated Oscillator) Third-overtone crystal operation. Notes 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……
