General Description

The MAX4760/MAX4760A/MAX4761/MAX4761A (DPDT)

analog switches operate from a single +1.8V to +5.5V

supply. These switches feature a low 54pF (typ)

capacitance for high-speed data switching applications.

The MAX4760/MAX4760A are quad double-pole/dou-

ble-throw (DPDT) switches, and the MAX4761/

MAX4761A are octal single-pole/double-throw (SPDT)

switches. They have eight 2.0Ω (typ) on-resistance,

low-capacitance switches to route audio and data sig-

nals. The MAX4760/MAX4760A have four logic inputs to

control the switches in pairs. The MAX4761/MAX4761A

have one logic control input and an enable input (EN)

to disable the switches.

The MAX4760/MAX4760A/MAX4761/MAX4761A are

available in a small 36-pin (6mm x 6mm) TQFN and

36-bump (3mm x 3mm) chip-scale package (UCSP™).
