Hex Schmitt Inverter

The MC74VHC14 is an advanced high speed CMOS Schmitt inverter

fabricated with silicon gate CMOS technology. It achieves high speed

operation similar to equivalent Bipolar Schottky TTL while maintaining

CMOS low power dissipation.

Pin configuration and function are the same as the MC74VHC04, but the

inputs have hysteresis and, with its Schmitt trigger function, the VHC14 can

be used as a line receiver which will receive slow input signals.

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 = 5.5ns (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: 60 FETs or 15 Equivalent Gates
