Description

General part information

MAX474 Series

The MAX4740/MAX4740H low on-resistance (0.61Ω typ) analog switches operate from a single 1.6V to 5.5V supply. The MAX4740/MAX4740H are quad, single-pole, double-throw (SPDT) switches and are configured to route audio signals. The MAX4740/MAX4740H are pin-to-pin compatible parts with the ST Microelectronics quad SPDT STG3699 analog switch.The MAX4740 is a quad SPDT switch and the MAX4740H is a quad SPDT switch that can be placed in a high-impedance mode. Switching logic is controlled by 2 control bits (CB1 and CB2). The MAX4740/MAX4740H also feature a low on-resistance match (0.06Ω) and low power-supply current (0.3µA), which increases battery life.The MAX4740/MAX4740H are available in a tiny 3mm x 3mm, 16-pin TQFN-EP, and 2.5mm x 2.5mm, 16-pin ultra-thin QFN packages.ApplicationsCellular PhonesNotebook ComputersPDAs and Other Handheld Devices
