TPMAX4644EUT+T

TECH PUBLIC · Analog Switches, Multiplexers · SOT-23-6

TPMAX4644EUT+T from TECH PUBLIC, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN input Channel select logic input. 1.8V logic compatible (VIH ≥ 1.6V at VCC=3.3-5.5V, VIH ≥ 1.4V at VCC=1.5-3.3V). IN=1 connects COM to NO; IN=0 connects COM to NC.
2 V+ power_in Positive supply voltage input, 1.8V to 5.5V operating range (absolute max -0.3V to +6.5V). Quiescent current <2uA typical.
3 GND power_in Ground reference (0 V).
4 NC passive Normally-closed switch throw. Connected to COM when IN=0. Independent input or output; bidirectional analog signal path with Ron ≈ 4Ω, ±128mA continuous current rating. Signal range -0.3V to +5.5V.
5 COM passive Common switch pole (labeled COM(A)). Common output or input, switched to either NO or NC by the IN pin. Bidirectional analog signal path with Ron ≈ 4Ω, ±128mA continuous current rating.
6 NO passive Normally-open switch throw. Connected to COM when IN=1. Independent input or output; bidirectional analog signal path with Ron ≈ 4Ω, ±128mA continuous current rating. Signal range -0.3V to +5.5V.
