2-Input NANDSchmitt-Trigger with
Open Drain Output
L74 VHC1G135
The L74VHC1G135 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 L74VHC1G135 to be used to interface 5V circuits to circuits of any
voltage between V CC and 7 V using an external resistor and power supply.
The L74VHC1G135 input structure provides protection when
voltages up to 7 V are applied, regardless of the supply
voltage. The L74VHC1G135 can be used to enhance noise immunity or to square up slowly changing waveforms.
High Speed: t PD = 4.9 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
