UNISONIC TECHNOLOGIES CO., LTD U74HC1G66 CMOS IC BILATERAL SWITCH DESCRIPTION The UTC U74HC1G66 is a high-speed Si-gate CMOS device that provides an analog switch. The switch has two input/output pins(Y and Z) and an active high enable input pin (E). When pin E is low, the analog switch is turned off. FEATURES * Operation voltage range: 2V~9V * Very low ON-resistance * Low power dissipation * Very small 5 pins package ORDERING INFORMATION Order Number Lead Free Halogen Free U74HC1G66L-AF5-R U74HC1G66G-AF5-R U74HC1G66L-AL5-R U74HC1G66G-AL5-R Package Packing SOT-25 SOT-353 Tape Reel Tape Reel MARKING www.unisonic.com.tw Copyright © 2011 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-276.D U74HC1G66 PIN CONFIGURATION VCC 5 1 Y CMOS IC E 4 2 Z 3 GND FUNCTION TABLE INPUT(EN) OUTPUT(Y/Z) H ON L OFF Note: H: HIGH voltage level; L: LOW voltage level.
