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.
