74LVC245A; 74LVCH245A

Octal bus transceiver; 3-state

Rev. 05 — 25 August 2009

Product data sheet

1. General description

The 74LVC245A; 74LVCH245A are 8-bit transceivers featuring non-inverting 3-state bus

compatible outputs in both send and receive directions. The device features an output

enable (OE) input for easy cascading and a send/receive (DIR) input for direction control.

OE controls the outputs so that the buses are effectively isolated.

Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be

applied to the outputs. These features allow the use of these devices in mixed

3.3 V and 5 V applications.

The 74LVCH245A bus hold on data inputs eliminates the need for external pull-up

resistors to hold unused inputs.

2. Features

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

Inputs accept voltages up to 5.5 V

High-impedance when V

= 0 V

Bushold on all data inputs (74LVCH245A only)

Complies with JEDEC standard no. 8-1A

ESD protection:

HBM JESD22-A114E exceeds 2000 V

MM JESD22-A115-A exceeds 200 V

Speciﬁed from

−40 °C

to +85

°C

and

−40 °C

to +125

°C
