LMH6574MAX

Texas Instruments · Signal Switches, Multiplexers, Decoders · SOIC-14

LMH6574MAX from Texas Instruments, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN0 input Input Channel 0, one of four multiplexer signal inputs selected by A1/A0 when EN and SD are low; signal and logic input pins are limited to ±(VS+0.6) V and ±20 mA.
2 GND power_in Ground pin.
3 IN1 input Input Channel 1, one of four multiplexer signal inputs selected by A1/A0 when EN and SD are low; signal and logic input pins are limited to ±(VS+0.6) V and ±20 mA.
4 GND power_in Ground pin.
5 IN2 input Input Channel 2, one of four multiplexer signal inputs selected by A1/A0 when EN and SD are low; signal and logic input pins are limited to ±(VS+0.6) V and ±20 mA.
6 V- power_in Negative supply; the recommended supply voltage is 6 V to 12 V (V+ − V−) with an absolute maximum of 13.2 V.
7 IN3 input Input Channel 3, one of four multiplexer signal inputs selected by A1/A0 when EN and SD are low; signal and logic input pins are limited to ±(VS+0.6) V and ±20 mA.
8 A0 input Select pin A0; together with A1 it chooses the active input channel per the truth table (A1 A0 = 00 selects CH0, 01 selects CH1, 10 selects CH2, 11 selects CH3 when EN and SD are low).
9 A1 input Select pin A1; together with A0 it chooses the active input channel per the truth table (A1 A0 = 00 selects CH0, 01 selects CH1, 10 selects CH2, 11 selects CH3 when EN and SD are low).
10 EN input Enable input; with EN high and SD low the output is disabled, per the truth table.
11 SD input Shutdown input; with SD high the device is in shutdown regardless of the other inputs, per the truth table.
12 FB input Feedback pin; external feedback and gain-setting resistors connect here to set the closed-loop gain.
13 OUT output Output pin; the datasheet summary states 80 mA of linear output current, and the absolute maximum IOUT is 130 mA (limited by power dissipation and a 150 °C junction temperature).
14 V+ power_in Positive supply; the recommended supply voltage is 6 V to 12 V (V+ − V−) with an absolute maximum of 13.2 V.
