Three SPDT switches in a 16-SOIC — what this part does
The MAX4053ESE+T from Analog Devices (formerly Maxim Integrated) is a triple SPDT analog switch — three independent 2:1 multiplexer/demultiplexer channels in a single 16-SOIC package. Each switch connects a common pin to one of two signal paths, controlled by a logic input. The on-state resistance is rated at 100 ohms max, with channel-to-channel matching held to 12 ohms max, so the insertion loss stays consistent across all three paths. Crosstalk between channels is specified at -90 dB at 100 kHz, which keeps audio or low-frequency analog signals from bleeding into adjacent channels. The switch handles single-supply rails from 2 V to 16 V, or dual supplies from ±2.7 V to ±8 V, making it usable in mixed-voltage systems without extra level translation.
Maximum turn-on time is 175 ns, turn-off 150 ns. Charge injection is 2 pC. Off-state leakage is 1 nA max.
Package and temperature grade — fits industrial control boards
The 16-SOIC (0.154" body width, 3.90 mm) is a standard footprint for analog switches — easy to route on a two-layer board and compatible with most pick-and-place machines.
