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

CD4053BMT from HGSEMI, 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 | IN/OUT by | passive | Analog switch channel by (bidirectional analog I/O), switched to common pin 15 when INH=0 and the channel-select inputs A, B, C select the y channel of the b pair. |
| 2 | IN/OUT bx | passive | Analog switch channel bx (bidirectional analog I/O), switched to common pin 15 when INH=0 and the channel-select inputs A, B, C select the x channel of the b pair. |
| 3 | IN/OUT cy | passive | Analog switch channel cy (bidirectional analog I/O), switched to common pin 4 when INH=0 and the channel-select inputs A, B, C select the y channel of the c pair. |
| 4 | OUT/IN cx OR cy | passive | Common analog I/O for the c switch pair, connected to channel cx or cy depending on the control inputs; analog input/output voltage range is 0 to VDD-VEE. |
| 5 | IN/OUT cx | passive | Analog switch channel cx (bidirectional analog I/O), switched to common pin 4 when INH=0 and the channel-select inputs A, B, C select the x channel of the c pair. |
| 6 | INH | input | Inhibit (enable control) input: when INH=0 the channel selected by A, B, C is ON; when INH=1 all channels are OFF. |
| 7 | VEE | power_in | Analog switch negative supply; recommended VDD-VEE range is 0 to 15 V and analog input/output voltages must stay within 0 to VDD-VEE. |
| 8 | VSS | power_in | Power supply ground (digital reference); the recommended DC supply range is VDD-VSS 3 V to 15 V, with absolute maximum 18 V. |
| 9 | C | input | Channel select control input C, which selects between the cx and cy channels; control input voltage range is 0 to VDD-VSS. |
| 10 | B | input | Channel select control input B, which selects between the bx and by channels; control input voltage range is 0 to VDD-VSS. |
| 11 | A | input | Channel select control input A, which selects between the ax and ay channels; control input voltage range is 0 to VDD-VSS. |
| 12 | IN/OUT ax | passive | Analog switch channel ax (bidirectional analog I/O), switched to common pin 14 when INH=0 and the channel-select inputs A, B, C select the x channel of the a pair. |
| 13 | IN/OUT ay | passive | Analog switch channel ay (bidirectional analog I/O), switched to common pin 14 when INH=0 and the channel-select inputs A, B, C select the y channel of the a pair. |
| 14 | OUT/IN ax OR ay | passive | Common analog I/O for the a switch pair, connected to channel ax or ay depending on the control inputs; analog input/output voltage range is 0 to VDD-VEE. |
| 15 | OUT/IN bx OR by | passive | Common analog I/O for the b switch pair, connected to channel bx or by depending on the control inputs; analog input/output voltage range is 0 to VDD-VEE. |
| 16 | VDD | power_in | Positive supply; recommended DC supply range VDD-VSS is 3 V to 15 V, with absolute maximum 18 V. |
