74LVC2G02DC
Dual 2-input NOR gate
1. General description
The 74LVC2G02 provides a 2-input NOR gate function.
Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these
devices as translators in a mixed 3.3 V and 5 V environment.
This device is fully specified for partial power-down applications using IOFF. The IOFF
circuitry disables the output, preventing a damaging backflow current through the device
when it is powered down.
2. Features and benefits Wide supply voltage range from 1.65 Vto 5.5V5 V tolerant outputs for interfacing with 5 V logic High noise immunity 24 mA output drive (VCC =3.0V) CMOS low power consumption Complies with JEDEC standard: JESD8-7 (1.65 Vto 1.95V) JESD8-5 (2.3 Vto 2.7V) JESD8-B/JESD36 (2.7 Vto 3.6V) Latch-up performance exceeds 250 mA Direct interface with TTL levels Inputs accept voltages up to 5V ESD protection: HBM JESD22-A114F exceeds 2000V MM JESD22-A115-A exceeds 200V Multiple package options Specified from 40 Cto +85 C and 40 Cto+125C
