# MC14052BDTR2G

**onsemi** · Analog Switches, Multiplexers · TSSOP-16

MC14052BDTR2G from onsemi, 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 | Y0 | passive | Y-section analog switch channel 0 (switch I/O), with recommended signal range 0 to VDD referenced to VEE. |
| 2 | Y2 | passive | Y-section analog switch channel 2 (switch I/O), with recommended signal range 0 to VDD referenced to VEE. |
| 3 | Y | passive | Y-section common O/I terminal of the switch, with recommended signal range 0 to VDD referenced to VEE. |
| 4 | Y3 | passive | Y-section analog switch channel 3 (switch I/O), with recommended signal range 0 to VDD referenced to VEE. |
| 5 | Y1 | passive | Y-section analog switch channel 1 (switch I/O), with recommended signal range 0 to VDD referenced to VEE. |
| 6 | INH | input | Inhibit control input referenced to VSS; with the input at logic high all switches are turned off, and unused inputs must be tied to VSS, VEE or VDD. |
| 7 | VEE | power_in | Negative supply for the analog switches, which must be less than or equal to VSS; VDD to VEE maximum is 18.0 V absolute, 15 V recommended. |
| 8 | VSS | power_in | Logic-low reference (ground) for the control inputs, which must be greater than or equal to VEE. |
| 9 | B | input | Binary channel-select control input referenced to VSS, with the logic high and low levels set by VDD and VSS. |
| 10 | A | input | Binary channel-select control input referenced to VSS, with the logic high and low levels set by VDD and VSS. |
| 11 | X3 | passive | X-section analog switch channel 3 (switch I/O), with recommended signal range 0 to VDD referenced to VEE. |
| 12 | X0 | passive | X-section analog switch channel 0 (switch I/O), with recommended signal range 0 to VDD referenced to VEE. |
| 13 | X | passive | X-section common O/I terminal of the switch, with recommended signal range 0 to VDD referenced to VEE. |
| 14 | X1 | passive | X-section analog switch channel 1 (switch I/O), with recommended signal range 0 to VDD referenced to VEE. |
| 15 | X2 | passive | X-section analog switch channel 2 (switch I/O), with recommended signal range 0 to VDD referenced to VEE. |
| 16 | VDD | power_in | Positive supply, specified from 3.0 V to 18 V (VDD referenced to VEE), with VDD at least VSS. |
