RS2251XTSS16 from Jiangsu RUNIC Tech, in a TSSOP-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 | X4 | bidirectional | Analog switch input/output channel 4. Selected when C,B,A = 1,0,0 with ENABLE low. Signal range GND to VCC; input/output pins are interchangeable. |
| 2 | X6 | bidirectional | Analog switch input/output channel 6. Selected when C,B,A = 1,1,0 with ENABLE low. Signal range GND to VCC. |
| 3 | X | bidirectional | Common analog switch 'X' terminal (mux common). Connects to the selected X0-X7 channel when ENABLE is low. Bidirectional; ~48 Ω typical on-resistance at 5 V. |
| 4 | X7 | bidirectional | Analog switch input/output channel 7. Selected when C,B,A = 1,1,1 with ENABLE low. Signal range GND to VCC. |
| 5 | X5 | bidirectional | Analog switch input/output channel 5. Selected when C,B,A = 1,0,1 with ENABLE low. Signal range GND to VCC. |
| 6 | ENABLE | input | Active-low digital enable input. Drive low to enable the selected channel; drive high to disconnect all channels (no channel on). VIH >= 1.7 V, VIL <= 0.5 V. Normally tied to GND if unused. |
| 7 | NC | unconnected | No connect. Leave floating or tie to GND. |
| 8 | GND | power_in | Ground return. Connect to digital ground / system 0 V reference. |
| 9 | C | input | Digital address input C (MSB of the 3-bit channel-select word). Combined with B and A to select one of X0-X7. VIH >= 1.7 V, VIL <= 0.5 V. |
| 10 | B | input | Digital address input B. Combined with C and A to select one of X0-X7. VIH >= 1.7 V, VIL <= 0.5 V. |
| 11 | A | input | Digital address input A (LSB of the 3-bit channel-select word). Combined with C and B to select one of X0-X7. VIH >= 1.7 V, VIL <= 0.5 V. |
| 12 | X3 | bidirectional | Analog switch input/output channel 3. Selected when C,B,A = 0,1,1 with ENABLE low. |
| 13 | X0 | bidirectional | Analog switch input/output channel 0. Selected when C,B,A = 0,0,0 with ENABLE low. |
| 14 | X1 | bidirectional | Analog switch input/output channel 1. Selected when C,B,A = 0,0,1 with ENABLE low. |
| 15 | X2 | bidirectional | Analog switch input/output channel 2. Selected when C,B,A = 0,1,0 with ENABLE low. |
| 16 | VCC | power_in | Positive analog and digital supply voltage. Operating range 2.5 V to 5.5 V; absolute max 6 V. Also sets the upper limit of the analog signal range on X/X0-X7. |
