74LV541A
Octal buffer/line driver; 3-state
Rev. 2 — 1 November 2016
Product data sheet
1. General description
The 74LV541A is an 8-bit buffer/line driver with 3-state outputs. The device features two
output enables (OE1 and OE2). A HIGH on OEn causes the associated outputs to
assume a high-impedance OFF-state.
Inputs are overvoltage tolerant. This feature allows the use of these devices as translators
in mixed voltage 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 I
OFF
. The I
OFF
circuitry disables the output, preventing the potentially damaging backflow current through
the device when it is powered down.

The minimum input voltage ratings may be exceeded if the input current ratings are observed.
The output voltage ratings may be exceeded if the output current ratings are observed.
This value is limited to 7.0 V maximum.
For TSSOP20 package: above 100
