Quad/Dual, Low-Voltage, Bidirectional RF Video Switches
_______________General Description
The MAX4545/MAX4546/MAX4547 are low-voltage
T-switches designed for switching RF and video signals
from DC to 300MHz in 50Ωand 75Ωsystems. The
MAX4545 contains four normally open single-pole/single-
throw (SPST) switches. The MAX4546 contains two dual
SPST switches (one normally open, one normally closed.)
The MAX4547 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
-80dB at 10MHz. They can handle Rail-to-Rail®analog sig-
nals in either direction. On-resistance (20Ωmax) is
matched between switches to 1Ωmax and is flat (0.5Ω
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.

_______________Theory of Operation
Logic-Level Translators

The MAX4545/MAX4546/MAX4547 are constructed as
high-frequency “T” switches, as shown in Figure 1. The
logic-level input, IN_, is translated by amplifier A1 into a
V+ to V- logic signal that drives amplifier A2. (Amplifier
A2 is an inverter for normally closed switches.)
Amplifier A2 drives the gates of N-channel MOSFETs
N1 and N2 from V+ to V-, turning them fully on or off.
The same signal drives inverter A3 (which drives the
P-channel MOSFETs P1 and P2) from V+ to V-, turning
them fully on or off, and drives the N-channel MOSFET
N3 off and on.
The logic-level threshold is determined by V+ and
GND_. The voltage on GND_ is usually at ground
potential, but it may be set to any voltage between
(V+ - 2V) and V-. When the voltage between V+ and
GND_ is less than 2V, the level translators become very
slow and unreliable. Since individual switches in each
package have individual GND_ pins, they may be set to
different voltages. Normally, however, they should all
be connected to the ground plane.itch On Condition
When the switch is on, MOSFETs N1, N2, P1, and P2
are on and MOSFET N3 is off. The signal path is COM_
to NO_, and because both N-channel and P-channel
MOSFETs act as pure resistances, it is symmetrical
(i.e., signals may pass in either direction). The off
MOSFET, N3, has no DC conduction, but has a small
amount of capacitance to GND_. The four on
MOSFETs also have capacitance to ground that,
together with the series resistance, forms a lowpass fil-
ter. All of these capacitances are distributed evenly
along the series resistance, so they act as a transmis-
sion line rather than a simple R-C filter. This helps to
explain the exceptional 300MHz bandwidth when the
switches are on.
