74LVC2G240
General description
The 74LVC2G240 is a dual inverting buffer/line driver with 3-state outputs. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH level at pins nOE causes the outputs to assume a high-impedance OFF-state. Schmitt trigger action at all inputs makes the circuit highly tolerant of slower input rise and fall times.
Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of the 74LVC2G240 as a translator in a mixed 3.3 V and 5 V environment.
It 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.
Features
- Wide supply voltage range from 1.65 V to 5.5 V
- 5 V tolerant input/output for interfacing with 5 V logic
- High noise immunity
- Complies with JEDEC standard:
- JESD8-7 (1.65 V to 1.95 V)
- JESD8-5 (2.3 V to 2.7 V)
- JESD8-B/JESD36 (2.7 V to 3.6 V)
- ESD protection:
- HBM JESD22-A114E exceeds 2000 V
- MM JESD22-A115-A exceeds 200 V
- +-24 mA output drive (VCC = 3.0 V)
- CMOS low power consumption
- Latch-up performance exceeds 250 mA
- Direct interface with TTL levels
- Inputs accept voltages up to 5 V
- Multiple package options
- Specified from -40 Cel to +85 Cel and -40 Cel to +125 Cel
