Product data sheet
1. General description
The 74LVC245A; 74LVCH245A 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 OE causes the outputs
to assume a high-impedance OFF-state. Inputs can be driven from either 3.3 V or 5 V devices. This
feature allows the use of these devices as translators in mixed 3.3 V and 5 V 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.
2. Features and benefits
5 V tolerant inputs/outputs for interfacing with 5 V logic
Wide supply voltage range from 1.2 V to 3.6 V
CMOS low-power consumption
Direct interface with TTL levels
Overvoltage tolerant inputs to 5.5 V
Bus hold on all data inputs (74LVCH245A only)
IOFF circuitry provides partial Power-down mode operation
Complies with JEDEC standard:
JESD8-7A (1.65 V to 1.95 V)
JESD8-5A (2.3 V to 2.7 V)
JESD8-C/JESD36 (2.7 V to 3.6 V)
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115B exceeds 200 V
CDM JESD22-C101E exceeds 1000 V
Specified from -40 °C to +85 °C and -40 °C to +125 °C
