UTC-IC U74LVC1G125

UNISONIC TECHNOLOGIES CO., LTD
U74LVC1G125
CMOS IC
BUS BUFFER/LINE DRIVER
3-STATE
DESCRIPTION
„
The U74LVC1G125 is a single bus buffer/line driver with 3-state
output. When the output enable ( ΟΕ ) is high the output will be
disabled. In contrast, when the ΟΕ is low, true data will pass from A
input to the Y output.
This device has power-down protective circuit to prevent the
device from destruction when it is powered down.
FEATURES
„
* Operate From 1.65V to 5.5V
* Inputs Accept Voltages to 5.5V
* High Noise Immunity
* Low Power Dissipation
* Direct Interface With TTL Level
