74LVC4245A

Octal dual supply translating transceiver; 3-state

Rev. 13 — 27 August 2021

Product data sheet

1. General description

The 74LVC4245A is an octal dual supply translating transceiver featuring 3-state bus compatible

outputs in both send and receive directions. It is designed to interface between a 3 V and 5 V

bus in a mixed 3 V and 5 V supply environment. The device features an output enable input (OE)

and a send/receive input (DIR) for direction control. A HIGH on OE causes the outputs to assume

a high-impedance OFF-state, effectively isolating the buses. In suspend mode, when either

supply is zero, there is no current path between supplies. V_CCA≥ V_CCB, except in suspend mode.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

2. Features and benefits

•

5 V tolerant inputs/outputs, for interfacing with 5 V logic

Wide supply voltage range:

•

•

CMOS low-power consumption

TTL interface capability at 3.3 V

Overvoltage tolerant control inputs to 5.5 V

High-impedance when V_CC(A)= 0 V

Complies with JEDEC standard no. JESD8B/JESD36

Latch-up performance meets requirements of JESD78 Class 1

ESD protection:

•

HBM JESD22-A114F exceeds 2000 V

MM JESD22-A115-A exceeds 200 V

•

Multiple package options

Specified from -40 °C to +85 °C and -40 °C to +125 °C

Definitions

Limiting values — Stress above one or more limiting values (as defined in

the Absolute Maximum Ratings System of IEC 60134) will cause permanent

damage to the device. Limiting values are stress ratings only and (proper)

operation of the device at these or any other conditions above those

given in the Recommended operating conditions section (if present) or the

Characteristics sections of this document is not warranted. Constant or

repeated exposure to limiting values will permanently and irreversibly affect

the quality and reliability of the device.

internal review and subject to formal approval, which may result in

modifications or additions. Nexperia does not give any representations or

warranties as to the accuracy or completeness of information included herein

and shall have no liability for the consequences of use of such information.

Short data sheet — A short data sheet is an extract from a full data sheet
