200 V Machine Model (JESD22-A115-A).
DESCRIPTION
The 74ALVC541 is a high-performance, low-power,
low-voltage, Si-gate CMOS device and superior to most
advanced CMOS compatible TTL families.
The 74ALVC541 is an octal non-inverting buffer/line driver
with 3-state bus compatible outputs. The 3-state outputs
are controlled by the output enable inputs OE
0
and OE
1
.
A HIGH on OE
n
causes the outputs to assume a
high-impedance OFF-state.

RECOMMENDED OPERATING CONDITIONS
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134); voltages are referenced to GND (ground = 0 V).
Notes
1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. When V
CC
= 0 V (Power-down mode), the output voltage can be 3.6 V in normal operation.
