MAXIM MAX4760, MAX4760A, MAX4761, MAX4761A Technical data

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/double-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 signals. 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™).

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.
