TC74AC393P,TC74AC393F,TC74AC393FN,TC74AC393FT
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.

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or
even destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/Derating Concept and Methods) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
Note 2: 500 mW in the range of Ta = −40 to 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C should be
applied up to 300 mW.

CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating
current consumption without load.
Average operating current can be obtained by the equation:
ICC (opr) = CPD·VCC·fIN + ICC/2 (per counter)
