Connections and external components shown in functional schematic are required. 0.1µF Capacitors need to be located near pins 32 & 33. Bias Voltages VCC Control Voltage 6 4. +5.5V -0.5V to VCC +0.5V Operation of this device above any one of these parameters may cause permanent damage. When the RF input is applied to the terminated port, the absolute maximum power is +30 dBm. Standard CMOS TTL interface, latch-up will occur if logic signal is applied prior to power supply.
