MC74VHC32
Quad 2-Input OR Gate
The MC74VHC32 is an advanced high speed CMOS 2input 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 7.0 V, allowing the interface of 5.0 V
systems to 3.0 V systems.
Features
High Speed: tPD = 3.8 ns (Typ) at VCC = 5.0 V
Low Power Dissipation: ICC = 2.0 mA (Max) at TA = 25°C
High Noise Immunity: VNIH = VNIL = 28% VCC
Power Down Protection Provided on Inputs
Balanced Propagation Delays
Designed for 2.0 V to 5.5 V Operating Range
Low Noise: VOLP = 0.8 V (Max)
Pin and Function Compatible with Other Standard Logic Families
Latchup Performance Exceeds 300 mA
ESD Performance:
Human Body Model > 2000 V;
Machine Model > 200 V
Chip Complexity: 48 FETs or 12 Equivalent Gates

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this highimpedance cir-
cuit. For proper operation, Vin and
Vout should be constrained to the
range GND v (Vin or Vout) v VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.

1. 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 /4 (per gate). CPD is used to determine the
noload dynamic power consumption; PD = CPD VCC2 fin + ICC VCC.
