Blocking capacitors are required. 4 Vdd Supply Voltage. 6, 7 GND This pin must be connected to RF/DC ground. Interface Schematic Typical Application Circuit SWITCHES - SMT 10 Notes: 1. Set logic gate and switch Vdd = +3V to +5V and use HCT series logic to provide a TTL driver interface. 2. Control inputs A/B can be driven directly with CMOS logic (HC) with Vdd of +3 to +8 Volts applied to the CMOS logic gates and to pin 4 of the RF switch. 3. DC Blocking capacitors are required for each RF port as shown. Capacitor value determines lowest frequency of operation. 4. Highest RF signal power capability is achieved with Vdd set to +8V. The switch will operate properly (but at lower RF power capability) at bias voltages down to +3V.
