| UNISONIC TECHNOLOGIES CO., LTD U74AHC1G66 BILATERAL SWITCH 3 2 1 CMOS IC DESCRIPTION The U74AHC1G66 is an analog switch which transmits signals from pin(Y or Z) to pin (Z or Y) with an active HIGH enable input pin (E). When pin E is LOW, the switch is turned off. 3 2 4 5 SOT-25 1 FEATURES * Operation voltage range: 2~5.5V * Low power dissipation * Very low ON-resistance: 26 (typ.) at Vcc=3.0V 16 (typ.) at Vcc=4.5V 14 (typ.) at Vcc=5.5V 5 4 SOT-353 *Pb-free plating product number: U74AHC1G66L ORDERING INFORMATION Order Number Normal Lead Free Plating U74AHC1G66-AF5-R U74AHC1G66L-AF5-R U74AHC1G66-AL5-R U74AHC1G66L-AL5-R Package SOT-25 SOT-353 Packing Tape Reel Tape Reel U74AHC1G66L-AF5-R (1)Packing Type (2)Package Type (3)Lead Plating (1) R: Tape Reel (2) AF5: SOT-25, AL5: SOT-353 (3) L: Lead Free Plating, Blank: Pb/Sn MARKING 3 2 A 66 4 5 1 Lead Plating www.unisonic.com.tw Copyright (c) 2005 Unisonic Technologies Co., Ltd 1 of 7 QW-R502-098,A U74AHC1G66 PIN CONFIGURATION GND 3 Z 2 Y 1 CMOS IC 4 E 5 VCC PIN DESCRIPTION PIN NUMBER 1 2 3 4 5 SYMBOL Y Z GND E Vcc DESCRIPTION independent input/output independent output/input ground enable input supply voltage FUNCTION TABLE (each gate) INPUT E H L SWITCH ON OFF LOGIC DIAGRAM (positive logic) E Y 4 1 2 E Z Y 4 # X1 1 1 1 1 X1 2 Z Vcc E Z Y UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 7 QW-R502-098,A U74AHC1G66 ABSOLUTE MAXIMUM RATINGS (unless otherwise specified)(Note 1) PARAMETER CMOS IC SYMBOL RATINGS UNIT Supply Voltage VCC -0.5~7 V Enable Input Voltage VE -0.5~7 V Enable Input Clamp Current IEK -20 mA Switch Diode Current ISK 20 mA On-State Switch Current(-0.5V PARAMETER Supply Voltage Enable Input Voltage Switch Voltage Input Transition Rise or Fall Rate Operating Temperature SYMBOL VCC VE VS t/v TA SYMBOL VIH VCC=2.0V VCC=3.0V VCC=5.5V VCC=2.0V VCC=3.0V VCC=5.5V VCC=5.5V, VE =VCC or GND TEST CONDITIONS CONDITIONS MIN 2 0 0 TYP 5.0 MAX 5.5 5.5 VCC 100 20 125 MAX UNIT V V V ns/V VCC=3.3+0.3V VCC=5.0+0.5V -40 MIN 1.5 2.1 3.85 25 TYP STATIC CHARACTERISTICS PARAMETER High-Level Input Voltage Low-Level Enable Input Leakage Current State Switch Current ON-Resistance (Peak) OFF ON VIL IE(LEAK) IS UNIT V 0.5 0.9 1.65 0.1 0.1 0.1 148 28 15 28 30 18 20 13 15 50 30 V A A A ON-Resistance (Rail) Quiescent Supply Current Enable Input Capacitance 2 10 pF Maximum Switch CS Independent I/O 4 10 pF Capacitance Note 4.
