U74LVC126A中文资料QUADRUPLE BUS BUFFER GATES WITH 3-STATE OUTPUTS数据手册UTC规格书

描述 Description

The U74LVC126A are quadruple bus buffer gates featuringindependent line drivers with 3-state outputs. When OE is low, thenY outputs are in a high-impedance state. When OE is high, thedevice passes non-inverted data from the nA input to its nY output.To ensure the high-impedance state during power up or powerdown, OE should be tied to GND through a pull-down resistor; theminimum value of the resistor is determined by the current-sinkingcapability of the driver.Inputs can be driven from either 3.3V to 5V devices. This featureallows the use of these devices as translators in a mixed 3.3V/5Vsystem environment.
