3.3 V octal buffer/line driver; 3-state
Rev. 7 — 17 August 2021
Product data sheet
1. General description
The 74LVT244A; 74LVTH244A is an 8-bit buffer/line driver with 3-state outputs. The device can
be used as two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and
2OE), each controlling four of the 3-state outputs. 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

[3] This is the bus hold overdrive current required to force the input to the opposite logic state.
[4] This parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 ms.
From VCC = 1.2 V to VCC = 3.3 V ± 0.3 V a transition time of 100 μs is permitted. This parameter is valid for Tamb = 25 °C only.
[5] ICC is measured with outputs pulled to VCC or GND.
[6] This is the increase in supply current for each input at the specified voltage level other than VCC or GND.

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
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
