CD74HCT4051M96 from Texas Instruments, in a SOP-16. 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 | A4 | bidirectional | Analog channel 4 in/out. Bidirectional analog switch terminal, connected to the COM pin when S2:S0 = 100 and Enable is asserted low. |
| 2 | A6 | bidirectional | Analog channel 6 in/out. Bidirectional analog switch terminal, connected to the COM pin when S2:S0 = 110 and Enable is asserted low. |
| 3 | COM | bidirectional | Common analog out/in. Shared switch terminal that connects to one of the eight A0-A7 channels selected by S0-S2. Analog switch is bidirectional so this pin can act as input or output. |
| 4 | A7 | bidirectional | Analog channel 7 in/out. Bidirectional analog switch terminal, connected to the COM pin when S2:S0 = 111 and Enable is asserted low. |
| 5 | A5 | bidirectional | Analog channel 5 in/out. Bidirectional analog switch terminal, connected to the COM pin when S2:S0 = 101 and Enable is asserted low. |
| 6 | ~{E} | input | Active-low enable input. When high, all eight analog switches are disabled (open); when low, the channel selected by S0-S2 is connected to COM. HCT logic thresholds: VIL = 0.8 V max, VIH = 2 V min. |
| 7 | VEE | power_in | Negative analog supply. Establishes the lower limit of the analog switch voltage range; VCC-VEE may be up to 10 V for HCT devices. Tie to GND for single-supply operation. |
| 8 | GND | power_in | Digital ground reference for logic inputs (S0-S2, E) and for the internal level-conversion circuitry. |
| 9 | S2 | input | Channel select bit 2 (MSB) of the 3-bit binary address selecting one of eight channels A0-A7. HCT-level input: VIL = 0.8 V max, VIH = 2 V min. |
| 10 | S1 | input | Channel select bit 1 of the 3-bit binary address selecting one of eight channels A0-A7. HCT-level input: VIL = 0.8 V max, VIH = 2 V min. |
| 11 | S0 | input | Channel select bit 0 (LSB) of the 3-bit binary address selecting one of eight channels A0-A7. HCT-level input: VIL = 0.8 V max, VIH = 2 V min. |
| 12 | A3 | bidirectional | Analog channel 3 in/out. Bidirectional analog switch terminal, connected to the COM pin when S2:S0 = 011 and Enable is asserted low. |
| 13 | A0 | bidirectional | Analog channel 0 in/out. Bidirectional analog switch terminal, connected to the COM pin when S2:S0 = 000 and Enable is asserted low. |
| 14 | A1 | bidirectional | Analog channel 1 in/out. Bidirectional analog switch terminal, connected to the COM pin when S2:S0 = 001 and Enable is asserted low. |
| 15 | A2 | bidirectional | Analog channel 2 in/out. Bidirectional analog switch terminal, connected to the COM pin when S2:S0 = 010 and Enable is asserted low. |
| 16 | VCC | power_in | Positive digital/analog supply, 4.5 V to 5.5 V for HCT variants. Sets the upper limit of the switch voltage range; VCC-VEE up to 10 V permitted. |
