74LVC245A; 74LVCH245A

Octal bus transceiver; 3-state

Rev. 12 — 16 September 2021

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 I_OFF. The I_OFFcircuitry

disables the output, preventing the potentially damaging backflow current through the device when

it is powered down.

2. Features and benefits

•

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)

I_OFFcircuitry 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
