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.
Switching speed and charge injection — what they mean for the signal path
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. The operating temperature range is -40°C to 85°C, which covers industrial control cabinets, outdoor telecom enclosures, and factory-floor sensor interfaces. The part is ROHS3 compliant, so it passes the material declaration for EU and RoHS-restricted markets.
Sourcing and lifecycle — active, no LTB risk
The MAX4053ESE+T carries an Active product status per the manufacturer. For a BOM line that needs a triple SPDT switch in a 16-SOIC, this part can be specified into new designs without worrying about a forced redesign in the next few years.
