Dual Binary Counter
The TC74HC393A is a high speed CMOS 4-BIT BINARY
COUNTER fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent
LSTTL 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 CK pulse. The counter can be reset to “0” (QA to QD = “L”) by
a high at the CLR input regardless of other inputs.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
• High speed: fmax = 72 MHz (typ.) at VCC = 5 V
• Low power dissipation: ICC = 4 μA (max) at Ta = 25°C
• High noise immunity: VNIH = VNIL = 28% VCC (min)
• Output drive capability: 10 LSTTL loads
• Symmetrical output impedance: |IOH| = IOL = 4 mA (min)
• Balanced propagation delays: tpLH ∼− tpHL
• Wide operating voltage range: VCC (opr) = 2 to 6 V
• Pin and function compatible with 74LS393
