Pin Descriptions Pin Number Function Description Interface Schematic 1 A See truth table and control voltage table. 2 B See truth table and control voltage table. 3, 5, 8 RFC, RF1, RF2 Typical Application Circuit This pin is DC coupled and matched to Ohms. Blocking capacitors are required. 4 Vdd Supply Voltage 6, 7 GND Package bottom must also be connected to PCB RF ground. Notes: 1. Set logic gate and switch Vdd = to 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 V set to. The switch will operate properly (but at lower RF power capability) at bias voltages down to. - 2 Alpha Road, Chelmsford, MA 1824 Phone: 978-2-3343 Fax: 978-2-3373
