TC74AC393P/F/FN/FT
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

Dual Binary Counter
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.
Features
• High speed: fmax = 180 MHz (typ.) at VCC = 5 V
• Low power dissipation: ICC = 8 µA (max) at Ta = 25°C
• High noise immunity: VNIH = VNIL = 28% VCC (min)
• Symmetrical output impedance: |IOH| = IOL = 24 mA (min)
Capability of driving 50 Ω
transmission lines.
• Balanced propagation delays: tpLH ∼− tpHL
• Wide operating voltage range: VCC (opr) = 2 to 5.5 V
• Pin and function compatible with 74F393
Note: xxxFN (JEDEC SOP) is not available in
Japan.

Note:
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)
