Description

CTRL = CMOS or TTL High

CTRL = CMOS or TTL Low

RFCommon to RF1

RFCommon to RF2

V_DD

Nominal +3 V supply connection.

CTRL

CMOS or TTL logic level:

The control logic input pin (CTRL) is typically

driven by a 3-volt CMOS logic level signal, and

has a threshold of 50% of V_DD. For flexibility to

support systems that have 5-volt control logic

drivers, the control logic input has been designed

to handle a 5-volt logic HIGH signal. (A minimal

current will be sourced out of the V_DDpin when the

control logic input voltage level exceeds V_DD.)

High = RFCommon to RF1 signal path

Low = RFCommon to RF2 signal path

GND

Ground connection. Traces should be

physically short and connected to ground

Latch-Up Avoidance

Unlike conventional CMOS devices, UltraCMOS™

devices are immune to latch-up.

Electrostatic Discharge (ESD) Precautions

Note 1: All RF pins must be DC blocked with an external

series capacitor or held at 0 V_DC

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 3.
