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 ORDERING INFORMATION Ordering Number U74LVC1G125G-AE5-R U74LVC1G125G-AF5-R U74LVC1G125G-AL5-R Package SOT-23-5 SOT-25 SOT-353 Packing Tape Reel Tape Reel Tape Reel MARKING www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-408.D U74LVC1G125 CMOS IC PIN CONFIGURATION VCC 5 1 OE Y 4 2 A 3 GND FUNCTION TABLE INPUT( ΟΕ ) INPUT(A) OUTPUT(Y) L L L L H H H X Z Note: H: HIGH voltage level; L: LOW voltage level; X=don’t care; Z=high-impedance OFF-state.
