Quad 2-Input OR Gate

The MC74VHC32 is an advanced high speed CMOS 2–input OR gate

fabricated with silicon gate CMOS technology. It achieves high speed

operation similar to equivalent Bipolar Schottky TTL while maintaining

CMOS low power dissipation.

The internal circuit is composed of three stages, including a buffer output

which provides high noise immunity and stable output. The inputs tolerate

voltages up to 7V, allowing the interface of 5V systems to 3V systems.

• High Speed: tPD = 3.8ns (Typ) at VCC = 5V

• Low Power Dissipation: ICC = 2µA (Max) at TA = 25°C

• High Noise Immunity: VNIH = VNIL = 28% VCC

• Power Down Protection Provided on Inputs

• Balanced Propagation Delays

• Designed for 2V to 5.5V Operating Range

• Low Noise: VOLP = 0.8V (Max)

• Pin and Function Compatible with Other Standard Logic Families

• Latchup Performance Exceeds 300mA

• ESD Performance: HBM > 2000V; Machine Model > 200V

• Chip Complexity: 48 FETs or 12 Equivalent Gates
