Inverter with Open Drain Output

The MC74VHC1G05 is an advanced high speed CMOS inverter with open drain output 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 an open drain output which provides the capability to set output switching level. This allows the MC74VHC1G05 to be used to interface 5 V circuits to circuits of any voltage between V CCand 7 V using an external resistor and power supply.

The MC74VHC1G05 input structure provides protection when voltages up to 7 V are applied, regardless of the supply voltage.
• High Speed: t PD = 3.8 ns (Typ) at V CC = 5 V
• Low Internal Power Dissipation: I CC = 2 mA (Max) at T A= 25°C
• Power Down Protection Provided on Inputs
• Pin and Function Compatible with Other Standard Logic Families
• Chip Complexity: FET = 105; Equivalent Gate = 26
