DESCRIPTION
The 74LVC1G125 is a high-performance, low-power,
low-voltage, Si-gate CMOS device, superior to most
advanced CMOS compatible TTL families.
The input can be driven from either 3.3 V or 5 V devices.
This feature allows the use of this device 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 74LVC1G125 provides one non-inverting buffer/line
driver with 3-state output. The 3-state output is controlled
by the output enable input (OE). A HIGH level at pin OE
causes the output 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 5.5 V in normal operation.
