SC04B

icman(晶尊微) · Touch Sensors · SOP-16

SC04B from icman(晶尊微), in a SOP-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 GND power_in Power supply ground pin for the device (电源地), with the VDD and GND pins forming the power inputs.
2 CMOD bidirectional Charge-collection capacitor connection that takes a fixed-value capacitor, typically 4.7 nF within a 1 nF to 10 nF range, independent of sensitivity.
3 CDC bidirectional Sensitivity capacitor connection with a 5 pF to 100 pF range, where a smaller capacitance gives higher sensitivity.
4 CIN0 bidirectional Sense-pad input for touch key 0 that detects the capacitance change, left floating when unused.
5 CIN1 bidirectional Sense-pad input for touch key 1 that detects the capacitance change, left floating when unused.
6 CIN2 bidirectional Sense-pad input for touch key 2 that detects the capacitance change, left floating when unused.
7 CIN3 bidirectional Sense-pad input for touch key 3 that detects the capacitance change, left floating when unused.
8 NC unconnected Listed as NC in the pin table with no function or connection specified in the datasheet.
9 NC unconnected Listed as NC in the pin table with no function or connection specified in the datasheet.
10 OUT3 output Open-drain NMOS output for touch key 3 with an internal 10 kΩ pull-up, where the valid active level is strong low and the pin is left floating when unused.
11 OUT2 output Open-drain NMOS output for touch key 2 with an internal 10 kΩ pull-up, where the valid active level is strong low and the pin is left floating when unused.
12 OUT1 output Open-drain NMOS output for touch key 1 with an internal 10 kΩ pull-up, where the valid active level is strong low and the pin is left floating when unused.
13 OUT0 output Open-drain NMOS output for touch key 0 with an internal 10 kΩ pull-up, where the valid active level is strong low and the pin is left floating when unused.
14 SLPEN input Sleep-mode enable input, where tying it to GND disables sleep and tying it to VDD allows the chip to enter sleep mode after no touch for more than 70 s.
15 MD input Output mode select input, where tying it to GND gives direct output (low while touched) and tying it to VDD gives latched output that toggles on each touch.
16 VDD power_in Positive supply input with an operating range of 2.6 V to 6.0 V and a maximum rating of 6.0 V.
