MAX14778

Dual ±25V Above- and Below-the-Rails

4:1 Analog Multiplexer

General Description

Beneﬁts and Features

● Wide Signal Range Supported from Single-Supply

The MAX14778 dual 4:1 analog multiplexer supports

analog signals up to ±25V with a single 3.0 to 5.5V

supply. Each multiplexer has separate control inputs to

allow independent switching, making the device ideal for

multiplexing different communications signals with the

same connector pins. Extended ESD protection of ±6kV

(Human Body Model) enable direct interfacing to cables

and connectors.

Voltage Eliminates Negative Power Supply

• ±25V Signal Range

• Single 3.0V to 5.5V Supply

● Two Independent Multiplexers

• Break-Before-Make Operation

• 1.5Ω R

• 3mΩ R

(max)

Flatness (typ)

The MAX14778 features a low 1.5Ω (max) on-resistance

and 3mΩ (typ) flatness to maximize signal integrity over

the entire common-mode voltage range. Each multiplexer

can carry up to 300mA of continuous current through the

multiplexer in either direction.

• 300mA Maximum Current Through Multiplexer

• 78pF Input Capacitance

• 75MHz Large-Signal Bandwidth

• 20-Pin TQFN (5mm x 5mm) Package

● Extended ESD Protection on A_ and B_ Pins

• ±6kV Human Body Model (HBM)

The MAX14778 supports switching of full-speed USB 1.1

signals (12Mbps) and RS-485 data rates of up to 20Mbps.

The MAX14778 is available in a 20-pin (5mm x 5mm)

TQFN package and is specified over the -40°C to +125°C

industrial temperature range.
