MC74VHC1G135
2-Input NAND
Schmitt-Trigger with
Open Drain Output
The MC74VHC1G135 is a single gate CMOS Schmitt NAND
trigger with an 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 the output switching
level. This allows the MC74VHC1G135 to be used to interface 5 V
circuits to circuits of any voltage between VCC and 7 V using an
external resistor and power supply.
The MC74VHC1G135 input structure provides protection when
voltages up to 7 V are applied, regardless of the supply voltage.
The MC74VHC1G135 can be used to enhance noise immunity or to
square up slowly changing waveforms.
Features
• High Speed: tPD = 4.9 ns (Typ) at VCC = 5 V
• Low Internal Power Dissipation: ICC = 1 mA (Max) at TA = 25°C
• Power Down Protection Provided on Inputs
• Pin and Function Compatible with Other Standard Logic Families
• Chip Complexity: FETs = 70; Equivalent Gates = 18
• Pb−Free Packages are Available
