74HC4851PW

Nexperia · Analog Switches, Multiplexers · TSSOP-16

74HC4851PW from Nexperia, in a TSSOP-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 Y4 bidirectional Independent analog input/output channel 4; connects to common Z when selected by S0 to S2 with E LOW, and is high-impedance OFF when E is HIGH.
2 Y6 bidirectional Independent analog input/output channel 6; connects to common Z when selected by S0 to S2 with E LOW, and is high-impedance OFF when E is HIGH.
3 Z bidirectional Common analog input/output; connected to the selected Yn channel when E is LOW.
4 Y7 bidirectional Independent analog input/output channel 7; connects to common Z when selected by S0 to S2 with E LOW, and is high-impedance OFF when E is HIGH.
5 Y5 bidirectional Independent analog input/output channel 5; connects to common Z when selected by S0 to S2 with E LOW, and is high-impedance OFF when E is HIGH.
6 E input Enable input, active LOW; when HIGH all switches are in the high-impedance OFF-state independent of S0 to S2.
7 n.c. unconnected Not connected.
8 GND power_in Ground (0 V) reference for all voltages on the device.
9 S2 input Select input (most significant bit of the channel select code); with S1 and S0 chooses which Yn channel connects to Z when E is LOW.
10 S1 input Select input (middle bit of the channel select code); with S2 and S0 chooses which Yn channel connects to Z when E is LOW.
11 S0 input Select input (least significant bit of the channel select code); with S2 and S1 chooses which Yn channel connects to Z when E is LOW.
12 Y3 bidirectional Independent analog input/output channel 3; connects to common Z when selected by S0 to S2 with E LOW, and is high-impedance OFF when E is HIGH.
13 Y0 bidirectional Independent analog input/output channel 0; connects to common Z when selected by S0 to S2 with E LOW, and is high-impedance OFF when E is HIGH.
14 Y1 bidirectional Independent analog input/output channel 1; connects to common Z when selected by S0 to S2 with E LOW, and is high-impedance OFF when E is HIGH.
15 Y2 bidirectional Independent analog input/output channel 2; connects to common Z when selected by S0 to S2 with E LOW, and is high-impedance OFF when E is HIGH.
16 VCC power_in Supply voltage: recommended 2.0 V to 6.0 V for 74HC4851 and 4.5 V to 5.5 V for 74HCT4851; absolute maximum VCC is 7.0 V.
