**Texas Instruments** · Analog Switches, Multiplexers · VSSOP-8-0.5mm

TS5A2053DCUR from Texas Instruments, in a VSSOP-8-0.5mm. 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 | COM | bidirectional | Analog common port; voltage range 0 to V+ (absolute maximum -0.5 to V+ + 0.5 V); ON-state resistance 7.5 Ω typical. |
| 2 | EN | input | Chip enable input (active low); logic threshold 0 to V+ × 0.3 V (low) or V+ × 0.7 to 5.5 V (high); 5-V tolerant. |
| 3 | GND | power_in | Digital ground; maximum continuous current -100 mA. |
| 4 | GND | power_in | Digital ground; maximum continuous current -100 mA. |
| 5 | IN | input | Digital control input; logic threshold 0 to V+ × 0.3 V (connects COM to NC) or V+ × 0.7 to 5.5 V (connects COM to NO). |
| 6 | NO | bidirectional | Normally open port; voltage range 0 to V+ (absolute maximum -0.5 to V+ + 0.5 V); ON-state resistance 7.5 Ω typical. |
| 7 | NC | unconnected | Normally closed port; voltage range 0 to V+ (absolute maximum -0.5 to V+ + 0.5 V); ON-state resistance 7.5 Ω typical. |
| 8 | V+ | power_in | Power supply; operating voltage 1.65 to 5.5 V (absolute maximum -0.5 to 6.5 V); maximum continuous current 100 mA. |
