Rev. 4 — 6 August 2021

Product data sheet

1. General description

The 74LVT162245B is a 16-bit transceiver with 30 Ω termination resistors and 3-state outputs. The

device can be used as two 8-bit transceivers or one 16-bit transceiver. The device features two

output enables (1OE and 2OE) each controlling eight outputs, and two send/receive (1DIR and

2DIR) inputs for direction control. A HIGH on nOE causes the outputs to assume a high-impedance

OFF-state. Bus hold data inputs eliminate the need for external pull-up resistors to define unused

inputs

2. Features and benefits

•

16-bit bidirectional bus interface

3-state buffers

•

Output capability: +12 mA/–12 mA

Wide supply voltage range from 2.7 to 3.6 V

BiCMOS high speed and output drive

Direct interface with TTL levels

Overvoltage tolerant inputs to 5.5 V

Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs

Live insertion/extraction permitted

Outputs include series resistance of 30 Ω making external termination resistors unnecessary

Power-up 3-state

No bus current loading when output is tied to 5 V bus

I_OFFcircuitry provides partial Power-down mode operation

Latch-up performance exceeds 500 mA per JESD 78 Class II Level B

Complies with JEDEC standards JESD8C (2.7 V to 3.6 V)

ESD protection:

•

HBM: JESD22-A114F exceeds 2000 V

MM: JESD22-A115-A exceeds 200 V

•

Specified from -40 °C to 85 °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.

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

with the same product type number(s) and title. A short data sheet is

intended for quick reference only and should not be relied upon to contain

detailed and full information. For detailed and full information see the relevant

full data sheet, which is available on request via the local Nexperia sales

office. In case of any inconsistency or conflict with the short data sheet, the
