MC74VHC1GT66 SPST (NO) Normally Open Analog Switch The MC74VHC1GT66 is a Single Pole Single Throw (SPST) analog switch. It achieves high speed propagation delays and low ON resistances while maintaining low power dissipation. This bilateral switch controls analog and digital voltages that may vary across the full power−supply range (from VCC to GND). The MC74VHC1GT66 is compatible in function to a single gate of the High Speed CMOS MC74VHCT4066 and the metal−gate CMOS MC14066. The device has bee.

MC74VHC1GT66 SPST (NO) Normally Open Analog Switch The MC74VHC1GT66 is a Single Pole Single Throw (SPST) analog switch. It achieves high speed propagation delays and low ON resistances while maintaining low power dissipation. This bilateral switch controls analog and digital voltages that may vary across the full power−supply range (from VCC to GND). The MC74VHC1GT66 is compatible in function to a single gate of the High Speed CMOS MC74VHCT4066 and the metal−gate CMOS MC14066. The device has been designed so that the ON resistances (RON) are much lower and more linear over input voltage than RON of the metal−gate CMOS or High Speed CMOS analog switches. The ON/OFF Control input is compatible with TTL−type input thresholds allowing the device to be used as a logic−level translator from 3 V CMOS logic to 5 V CMOS logic or from 1.8 V CMOS logic to 3 V CMOS logic while operating at the high−voltage power supply. The input protection circuitry on this device allows overvoltage tolerance on the input, which provides protection when voltages of up to 7 V are applied, regardless of the supply voltage. This allows the MC74VHC1GT66 to be used to interface 5 V circuits to 3 V circuits. Features • High Speed: tPD = 20 ns (Typ) at VCC = 5 V • Low Power Dissipation: ICC = 1.0 mA (Max) at TA = 25°C • Diode Protection Provided on Inputs and Outputs • Improved Linearity and Lower ON Resistance over Input Voltage • On/Off Control Input Has OVT • Chip Complexity: FETs = 11; Equivalent Gates = 3 • Pb−Free Packages are Available 5 1 http://onsemi.com SC−88A DF SUFFIX CASE 419A M MARKING DIAGRAMS 5 VE MG G 1 5 1 TSOP−5 DT SUFFIX CASE 483 5 VE MG G 1 VE = Device Code M = Date Code* W = Work Week G = Pb−Free Package (Note: Microdot may be in either location) *Date Code orientation and/or position may vary depending upon manufacturing location.
