74LVCE1G126
SINGLE BUFFER GATE WITH 3-STATE OUTPUT
Description
Pin Assignments
The 74LVCE1G126 is a single non-inverting buffer/bus driver
with a 3-state output. The output enters a high impedance
state when a LOW-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
environment. The device is fully specified for partial power
down applications using IOFF. The IOFF circuitry disables the
output preventing damaging current backflow when the device
is powered down.
