U74HCT1G66UNISONIC TECHNOLOGIES CO., LTDBILATERAL SWITCHCMOS IC• DESCRIPTIONThe U74HCT1G66 is a high-speed Si-gate CMOS devicethat provides an analog switch. The switch has two input/outputpins(Y and Z) and an active high enable input pin (E). When pin Eis low, the analog switch is turned off.• FEATURES* Operation voltage range: 2V~9V* Very low ON-resistance* Low power dissipation* Very small 5 pins package54123SOT-25• ORDERING INFORMATIONOrdering NumberPackagePackingLead FreeHalogen FreeU74HCT1G66L-AF5-R U74HCT1G66G-AF5-R SOT-25 Tape Reel• MARKINGwww.unisonic.com.tw 1 of 5Copyright © 2011 Unisonic Technologies Co., LtdQW-R502-277.C
