CD74HC4316M96 from Texas Instruments, in a SOIC-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 | 1Z | bidirectional | Analog input/output of switch 1 (Z side). Swings between VEE and VCC when the switch is enabled; presents high impedance when the switch is off. |
| 2 | 1Y | bidirectional | Analog input/output of switch 1 (Y side). Connected to 1Z through the analog switch when 1S is high and E is low. |
| 3 | 2Y | bidirectional | Analog input/output of switch 2 (Y side). Connected to 2Z when switch 2 is enabled. |
| 4 | 2Z | bidirectional | Analog input/output of switch 2 (Z side). Signal range VEE..VCC. |
| 5 | 2S | input | Digital control for switch 2. Logic high (with E low) closes switch 2; logic low opens it. Input swings between GND and VCC. |
| 6 | 3S | input | Digital control for switch 3. Logic high (with E low) closes switch 3. |
| 7 | E | input | Active-low common enable. When E is low each switch responds to its own S control input; when E is high all four switches are forced OFF. |
| 8 | GND | power_in | Digital ground reference (0 V). Reference for the S and E control-logic inputs. |
| 9 | VEE | power_in | Negative analog supply. Sets the lower limit of the analog signal range. 0 V to -6 V recommended; VCC-VEE must be 2 V to 10 V. |
| 10 | 3Z | bidirectional | Analog input/output of switch 3 (Z side). Signal range VEE..VCC. |
| 11 | 3Y | bidirectional | Analog input/output of switch 3 (Y side). Connected to 3Z when switch 3 is enabled. |
| 12 | 4Y | bidirectional | Analog input/output of switch 4 (Y side). Connected to 4Z when switch 4 is enabled. |
| 13 | 4Z | bidirectional | Analog input/output of switch 4 (Z side). Signal range VEE..VCC. |
| 14 | 4S | input | Digital control for switch 4. Logic high (with E low) closes switch 4. |
| 15 | 1S | input | Digital control for switch 1. Logic high (with E low) closes switch 1. |
| 16 | VCC | power_in | Positive supply. Powers the level-translation and control logic and sets the upper limit of the analog signal range. 2 V to 6 V (HC); VCC-VEE up to 10 V. |
