The 74LV245A is an 8-bit transceiver with 3-state outputs. The device features an output enable (OE) and send/receive (DIR) for direction control. A HIGH on OEcauses the outputs to assume a high-impedance OFF-state.
Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.
This device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.
Features and benefits
Wide supply voltage range from 2.0 V to 5.5 V
Maximum tpd of 6.5 ns at 5 V
Typical VOL(p) < 0.8 V at VCC = 3.3 V, Tamb = 25 °C
Typical VOH(v) > 2.3 V at VCC = 3.3 V, Tamb = 25 °C
Supports mixed-mode voltage operation on all ports
IOFF circuitry provides partial Power-down mode operation
Latch-up performance exceeds 250 mA per JESD 78 Class II
ESD protection:
HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 3000 V
CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 2000 V
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
