Dual Binary Counter

The TC74VHC393 is an advanced high speed CMOS 4-BIT

BINARY COUNTER fabricated with silicon gate 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.

An input protection circuit ensures that 0 to 5.5 V can be

applied to the input pins without regard to the supply voltage.

This device can be used to interface 5 V to 3 V systems and two

supply systems such as battery back up. This circuit prevents

device destruction due to mismatched supply and input voltages.

Features

• High speed: fmax = 170 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)

• Power down protection is provided on all inputs.

• Balanced propagation delays: tpLH ∼− tpHL

• Wide operating voltage range: VCC (opr) = 2 to 5.5 V

• Low noise: VOLP = 0.8 V (max)

• Pin and function compatible with 74ALS393
