74LVCE1G125
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
state when a HIGH-level is applied to the output enable (OE)
pin. The device is designed for operation with a power supply
range of 1.4V to 5.5V.
The inputs are tolerant to 5.5V
allowing this device to be used in a mixed voltage
