74LVC125A

Quad 3-State Buffer, OE LOW

Contact Sales

Description

The 74LVC125A provides four independent buffers with three state outputs. Each output is independently controlled by an associated output enable pin (OE) which places the device in the high impedance state when driven high. The device is designed for operation with a power supply range of 1.65V 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 I_OFF. The I_OFFcircuitry disables the output preventing damaging current backflow when the device is powered down.

Feature(s)

Supply Voltage Range from 1.65V to 5.5V
Sinks 24mA at V_CC= 3.3V
CMOS low power consumption
I_OFF Supports Partial-Power-Down Mode Operation
Inputs or outputs accept up to 5.5V
