| LESHAN RADIO COMPANY, LTD. ANALOG Switch MC74VHC1GT66 The MC74VHC1GT66 is an advanced high speed CMOS bilateral analog switch fabricated with silicon gate CMOS technology. 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 very High Speed CMOS MC74VHCT4066. The device has been designed so that the ON resistances (RON) are much lower and more linear over input voltage. The ON/OFF Control input is compatible with TTL-type input thresholds allowing the device to be used as a logic-level translator from 3.0 V CMOS logic to 5.0 V CMOS logic or from 1.8 V CMOS logic to 3.0 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. * High Speed: t PD = 20 ns (Typ) at V CC = 5 V * Low Power Dissipation: I CC = 2 A (Max) at T A = 25C * Diode Protection Provided on Inputs and Outputs * Improved Linearity and Lower ON Resistance over Input Voltage * On/Off Control Input Has OVT MARKING DIAGRAMS 5 4 1 2 3 VEd SC-70/SC-88A/SOT-353 DF SUFFIX CASE 419A Pin 1 d = Date Code 5 4 Figure 1.

C PD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: I CC(OPR) = C PD * V CC * f in + I CC . C PD is used to determine the no- load dynamic power consumption; P D = C PD * V CC 2 * f in + I CC * V CC . VHT66-3/6 LESHAN RADIO COMPANY, LTD.
