Product Overview
The TS5A3357 is a Texas Instruments SP3T analog switch multiplexer for Signal_Chain designs. Its switch structure is a 1-channel 3:1 multiplexer/demultiplexer, also described as 1x SP3T, allowing one common signal path to be connected to one of three normally open channels under digital control.
The device operates over a recommended supply range of 1.65 to 5.5 V, with an analog voltage range from 0 to V+ on the NO and COM pins. Digital control inputs support 0 to 5.5 V, with logic thresholds of 0.7 x V+ minimum for high and 0.3 x V+ maximum for low. Absolute maximum supply rating is -0.5 to 6.5 V.
Performance parameters include 5 ohm typical ON resistance at V+=4.5 V and VNO=0 V, 15 ohm maximum peak ON resistance over -40°C to 85°C, and 0.1 ohm typical ON-resistance channel matching. Dynamic and signal metrics include 6.5 ns typical turn-on time, 3.7 ns typical turn-off time, 334 MHz typical bandwidth, -82 dB typical OFF isolation, and 3.4 pC typical charge injection. The package is VSSOP-8 (DCU), 2.3 mm x 2 mm nominal body.
