High-Bandwidth, Quad DPDT Switches
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™).

Note 1:
Signals on NO_, NC_, COM_ exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current to maximum
current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

UCSP packages are 100% tested at +25°C and limits across the full temperature range are guaranteed by correlation and
design. TQFN packages are 100% tested at +85°C and limits across the full temperature range are guaranteed by correla-
