SINGLE BUFFER GATE WITH 3-STATE OUTPUT
Description Pin Assignments
(Top View)
The 74LVCE1G125 is a single non-inverting buffer/bus driver
with a 3-state output. The output enters a high impedance
1 5 Vcc
OE
state when a HIGH-level is applied to the output enable (OE)
pin. The device is designed for operation with a power supply
A 2
range of 1.4V to 5.5V. The inputs are tolerant to 5.5V
allowing this device to be used in a mixed voltage
3 4 Y
GND
environment. The device is fully specified for partial power
down applications using I . The I circuitry disables the
OFF OFF
SOT25 / SOT353
output preventing damaging current backflow when the device
is powered down.
