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.
The oscillator is designed to operate either in the fundamental or third overtone mode depending on the crystal and external components applied.
On-chip September 1993 CPD SYMBOL tPHL/tPLH PARAMETER propagation delay X1 to OUT (S1 = S2 = LOW) maximum clock frequency input capacitance except X1 and X2 power dissipation capacitance per package capacitors minimize external component count for third overtone crystal applications.
The oscillator may be replaced by an external clo...
