Table 2. Pin Descriptions

Absolute Maximum Ratings are those values

listed in the above table. Exceeding these values

may cause permanent device damage.

No.

Name

Description

RF2

RF2 port.¹

Functional operation should be restricted to the

limits in the DC Electrical Specifications table.

Exposure to absolute maximum ratings for

extended periods may affect device reliability.

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.

RF1

V_DD

RF1 port.¹

Control Logic Input

Nominal 3 V supply connection.

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.

CTRL

CMOS or TTL logic level:

High = RFC to RF1 signal path

Low = RFC to RF2 signal path

Common RF port for switch.¹

RFC

Notes: 1. All RF pins must be DC blocked with an external series

capacitor or held at 0 V_DC

Electrostatic Discharge (ESD) Precautions

0.7xV_DD

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.
