_______________General Description

The MAX4565/MAX4566/MAX4567 are low-voltage

T-switches designed for switching RF and video signals

from DC to 350MHz in 50

Ω and 75Ω systems. The

MAX4565 contains four normally open single-pole/single-

throw (SPST) switches. The MAX4566 contains two dual

SPST switches (one normally open, one normally closed.)

The MAX4567 contains two single-pole/double-throw

(SPDT) switches.

Each switch is constructed in a “T” configuration, ensuring

excellent high-frequency off isolation and crosstalk of

nals in either direction. On-resistance (60

Ω max) is

matched between switches to 2.5

Ω max and is flat (2Ω

max) over the specified signal range, using ±5V supplies.

The off leakage current is less than 5nA at +25°C and

50nA at +85°C.

These CMOS switches can operate with dual power sup-

plies ranging from ±2.7V to ±6V or a single supply

between +2.7V and +12V. All digital inputs have 0.8V/2.4V

logic thresholds, ensuring both TTL- and CMOS-logic com-

patibility when using ±5V or a single +5V supply.
