UNISONIC TECHNOLOGIES CO., LTD U74LVC1G126 CMOS IC BUS BUFFER/LINE DRIVER; 3-STATE DESCRIPTION The U74LVC1G126 is single bus buffer/line driver with 3-state output. The output is disabled When the output enable (OE) is low. When OE is high, true data is will pass A input to the Y output. This device has power-down protective circuit preventing 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 ORDERING INFORMATION Ordering Number Lead Free U74LVC1G126L-AE5-R U74LVC1G126L-AF5-R U74LVC1G126L-AL5-R Halogen Free U74LVC1G126G-AE5-R U74LVC1G126G-AF5-R U74LVC1G126G-AL5-R Package Packing SOT-23-5 SOT-25 SOT-353 Tape Reel Tape Reel Tape Reel MARKING 5 4 3L6 1 2 3 G: Halogen Free L:Lead Free www.unisonic.com.tw Copyright © 2011 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-398.C U74LVC1G126 PIN CONFIGURATION VCC 5 1 OE CMOS IC Y 4 2 A 3 GND FUNCTION TABLE INPUT(OE) INPUT(A) OUTPUT(Y) H L L H H H L X Z Note: H: HIGH voltage level; L: LOW voltage level; X=don’t care; Z=high-impedance OFF-state.
