UNISONIC TECHNOLOGIES CO., LTD U74AUC1G126 CMOS IC SINGLE BUS BUFFER GATE WITH 3-STATE OUTPUT DESCRIPTION The U74AUC1G126 is single bus buffer gate with 3-state output. The output is disabled When the output enable (OE) is low. When OE is high, true data is passed from A input to the Y output. This device has power-down protective circuit, preventing device destruction when it is powered down. FEATURES * Operate from 0.8V to 2.7V * Low power dissipation: ICC=10μA (Max.) * ±8mA Output Driver : VCC=1.8V * Ioff Supports partial-Power-Down Mode Operation ORDERING INFORMATION Ordering Number U74AUC1G126G-AE5-R U74AUC1G126G-AL5-R Package SOT-23-5 SOT-353 Packing Tape Reel Tape Reel MARKING www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 5 QW-R126-017.B U74AUC1G126 PIN CONFIGURATION FUNCTION TABLE CMOS IC INPUT(OE) INPUT(A) OUTPUT(Y) H H H H L L L X Z Note: H: HIGH voltage level; L: LOW voltage level; X=don’t care; Z=high-impedance OFF-state.
