MPC509AU

Texas Instruments · Analog Switches, Multiplexers · SOIC-16

MPC509AU from Texas Instruments, in a SOIC-16. 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 A0 input Channel address input bit 0 (with A1) selects the ON channel pair; logic low threshold 0.8V, high threshold 4.0V.
2 EN input Enable input: logic 1 allows the addressed channel pair to be ON, logic 0 turns all channels OFF; tie to +VSUPPLY if unused.
3 -VSUPPLY power_in Negative supply pin; supplies are specified at -15V, with V- to ground limited to 25V and 44V maximum between supply pins.
4 In 1A passive Analog input channel 1A, signal range ±15V, withstands 70VPP overvoltage and presents 1kΩ if power is lost.
5 In 2A passive Analog input channel 2A, signal range ±15V, withstands 70VPP overvoltage and presents 1kΩ if power is lost.
6 In 3A passive Analog input channel 3A, signal range ±15V, withstands 70VPP overvoltage and presents 1kΩ if power is lost.
7 In 4A passive Analog input channel 4A, signal range ±15V, withstands 70VPP overvoltage and presents 1kΩ if power is lost.
8 Out A passive Differential multiplexer output A, connected to the selected In A channel through RON of 1.3kΩ typ at 25°C.
9 Out B passive Differential multiplexer output B, connected to the selected In B channel through RON of 1.3kΩ typ at 25°C.
10 In 4B passive Analog input channel 4B, signal range ±15V, withstands 70VPP overvoltage and presents 1kΩ if power is lost.
11 In 3B passive Analog input channel 3B, signal range ±15V, withstands 70VPP overvoltage and presents 1kΩ if power is lost.
12 In 2B passive Analog input channel 2B, signal range ±15V, withstands 70VPP overvoltage and presents 1kΩ if power is lost.
13 In 1B passive Analog input channel 1B, signal range ±15V, withstands 70VPP overvoltage and presents 1kΩ if power is lost.
14 +VSUPPLY power_in Positive supply pin; supplies are specified at +15V, with V+ to ground limited to 22V.
15 GND power_in Ground reference pin for the device.
16 A1 input Channel address input bit 1 (with A0) selects the ON channel pair; logic low threshold 0.8V, high threshold 4.0V.
