74LVC2G38
Rev. 13 — 3 July 2017
Dual 2-input NAND gate; open drain
Product data sheet
1
General description
The 74LVC2G38 provides a 2-input NAND function.
The outputs of the 74LVC2G38 devices are open-drain and can be connected to other
open-drain outputs to implement active-LOW, wired-OR or active-HIGH wired-AND
functions.
Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of
these devices as translators in a mixed 3.3 V and 5 V environment.
This device is fully specified for partial power-down applications using I
OFF
. The I
OFF
circuitry disables the output, preventing the damaging backflow current through the
device when it is powered down.

The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
When V
CC
= 0 V (Power-down mode), the output voltage can be 5.5 V in normal operation.
For TSSOP8 package: above 55 °C the value of P
tot
derates linearly with 2.5 mW/K.
For VSSOP8 package: above 110 °C the value of P
tot
derates linearly with 8 mW/K.
For XSON8 and XQFN8 packages: above 118 °C the value of P
tot
derates linearly with 7.8 mW/K.
For X2SON8 package: above 118 °C the value of P
