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 IOFF. The IOFF circuitry
disables the output, preventing the potentially damaging backflow current through the device when
it is powered down.

[2] The bus hold circuit is switched off when VI ˃ VCC allowing 5.5 V on the input terminal.
[3] For I/O ports the parameter IOZ includes the input leakage current.
[4] Valid for data inputs of bus hold parts only (74LVCH245A). Note that control inputs do not have a bus hold circuit.
[5] The specified sustaining current at the data input holds the input below the specified VI level.
[6] The specified overdrive current at the data input forces the data input to the opposite input state.

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.
Draft — The document is a draft version only. The content is still under
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
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

customer (a) shall use the product without Nexperia’s warranty of the
product for such automotive applications, use and specifications, and (b)
whenever customer uses the product for automotive applications beyond
Nexperia’s specifications such use shall be solely at customer’s own risk,
and (c) customer fully indemnifies Nexperia for any liability, damages or failed
product claims resulting from customer design and use of the product for
automotive applications beyond Nexperia’s standard warranty and Nexperia’s
product specifications.
