TC74AC390P/F/FN
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74AC390P,TC74AC390F,TC74AC390FN
Dual Decade Counter
The TC74AC390 is an advanced high speed CMOS DUAL
DECADE 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 consists of two independent 4-bit counters, each composed of
a divide-by-two and a divide-by-five counter. The divide-by-two
counter is incremented on the negative going transition of clock A
( CKA ). The divided-by-five counter is incremented on the
negative going transition of clock B ( CKB ). The counter can be
cascaded to form decade, bi-quinary, or various combinations up
to a divide-by-100 counter. When the CLEAR input is set high,
the Q outputs are set to low independent of the clock inputs.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Note: xxxFN (JEDEC SOP) is not available in
Japan.
