MC74LVX8051DTR2G from onsemi, 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 input/output channel 4. Bidirectional analog switch pin routed to common X (pin 3) when A=0,B=0,C=1. |
| 2 | X6 | bidirectional | Analog input/output channel 6. Bidirectional analog switch pin routed to common X (pin 3) when A=0,B=1,C=1. |
| 3 | X | bidirectional | Common analog output/input. The selected X0-X7 channel is connected here through the on-resistance (Ron typ 15-25 Ω). |
| 4 | X7 | bidirectional | Analog input/output channel 7. Bidirectional analog switch pin routed to common X (pin 3) when A=1,B=1,C=1. |
| 5 | X5 | bidirectional | Analog input/output channel 5. Bidirectional analog switch pin routed to common X (pin 3) when A=1,B=0,C=1. |
| 6 | Enable | input | Active-LOW enable input. When LOW, the selected channel is connected to the common X pin; when HIGH, all analog switches are OFF (high impedance). CMOS-compatible logic input referenced to GND/VCC. |
| 7 | NC | unconnected | No connect. Leave floating. |
| 8 | GND | power_in | Ground / negative supply reference (0 V). Analog signal excursions on X and X0-X7 must remain between GND and VCC (2.5-6.0 V rail). |
| 9 | C | input | Channel-select input C (MSB of the 3-bit select). Combined with A and B to select one of X0-X7. CMOS-compatible; VIH ≥ 3.15 V at VCC=4.5 V. |
| 10 | B | input | Channel-select input B (middle bit of the 3-bit select). Combined with A and C to select one of X0-X7. |
| 11 | A | input | Channel-select input A (LSB of the 3-bit select). Combined with B and C to select one of X0-X7. |
| 12 | X3 | bidirectional | Analog input/output channel 3. Bidirectional analog switch pin routed to common X (pin 3) when A=1,B=1,C=0. |
| 13 | X0 | bidirectional | Analog input/output channel 0. Bidirectional analog switch pin routed to common X (pin 3) when A=0,B=0,C=0. |
| 14 | X1 | bidirectional | Analog input/output channel 1. Bidirectional analog switch pin routed to common X (pin 3) when A=1,B=0,C=0. |
| 15 | X2 | bidirectional | Analog input/output channel 2. Bidirectional analog switch pin routed to common X (pin 3) when A=0,B=1,C=0. |
| 16 | VCC | power_in | Positive DC supply, 2.5 to 6.0 V referenced to GND. Also sets the upper bound for analog signal excursion on X and X0-X7. Bypass with a local ceramic capacitor. |
