Dual Binary Counter
Note:
The TC74AC393 is an advanced high speed CMOS 4-BIT
BINARY COUNTER fabricated with silicon gate and
double-layer metal wiring C2MOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
It contains two independent counter circuits in one package, so
that counting or frequency division of eight binary bits can be
achieved with one IC.
This device changes state on the negative going transition of
the CLOCK pulse. The counter can be reset to “0” (QA to QD =
“L”) by a high at the CLEAR input regardless of other inputs.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
xxxFN (JEDEC SOP) is not available in
Japan.
