Pin Descriptions Table 4. Absolute Maximum Ratings Electrostatic Discharge (ESD) Precautions When handling this UltraCMOS™ device, observe the same precautions that you would use with other ESD-sensitive devices. Although this device contains circuitry to protect it from damage due to ESD, precautions should be taken to avoid exceeding the rating specified in Table 4. Latch-Up Avoidance Unlike conventional CMOS devices, UltraCMOS™ devices are immune to latch-up. Table 3. Operating Ranges Notes: 1. All RF pins must be DC blocked with an external series capacitor or held at 0 VDC. Figure 3. Pin Configuration Table 5. Control Logic Truth Table Exceeding absolute maximum ratings may cause permanent damage. Operation should be restricted to the limits in the Operating Ranges table. Operation between operating range maximum and absolute maximum for extended periods may reduce reliability. Exposed Solder Pad - Shorted to Pin 2 (bottom side) RF2 GND RF1 RFC CTRL V DD 4 5 6 3 2 1 Pin No. Pin Name Description 1 RF2 RF2 port.1 2 GND Ground Connection. Traces should be physically short and connected to the ground plane. This pin is connected to the exposed solder pad that also must be soldered to the ground plane for best performance. 3 RF1 RF1 port.1 4 VDD Nominal 3 V supply connection. 5 CTRL CMOS or TTL logic level: High = RFC to RF1 signal path Low = RFC to RF2 signal path 6 RFC Common RF port for switch.1 Symbol Parameter/Conditions Min Max Units VDD Power supply voltage -0.3 4.0 V VI Voltage on any input except for the CTRL input -0.3 VDD+ 0.3 V VCTRL Voltage on CTRL input 5.0 V TST Storage temperature range -65 150 °C P IN Input power (50 Ω) 35 dBm VESD ESD voltage (Human Body Model) 250 V Parameter Min Typ Max Units VDD Power Supply Voltage 2.7 3.0 3.3 V IDD Power Supply Current (VDD = 3V, VCNTL = 3V) 29 35 µA Control Voltage High 0.7xVDD V Control Voltage Low 0.3xVDD V TOP Operating temperature range -40 85 °C Control Voltage Signal Path CTRL = CMOS or TTL High RFC to RF1 CTRL = CMOS or TTL Low RFC to RF2 Control Logic Input The control logic input pin (CTRL) is typically driven by a 3-volt CMOS logic level signal. For flexibility to support systems that have 5-volt control logic drivers, the control logic input has been designed to handle a standard 5-volt TTL control signal. This TTL control signal input must not exceed 5-volts or damage to the switch could result. |
