SN74CB3Q3253PWR from Texas Instruments, 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 | 1OE | input | Output Enable 1 Active-Low input; when low, multiplexer 1 is enabled and A port connects to selected B port (0V to 5.5V TTL/CMOS compatible). |
| 2 | S1 | input | Select Pin 1 input; selects channel for multiplexer 1 in combination with S0 (0V to 5.5V TTL/CMOS compatible). |
| 3 | 1B4 | bidirectional | Multiplexer 1 channel 4 I/O port; supports rail-to-rail 0V to 5V signal levels with bidirectional data flow and typical ON-state resistance of 4Ω. |
| 4 | 1B3 | bidirectional | Multiplexer 1 channel 3 I/O port; supports rail-to-rail 0V to 5V signal levels with bidirectional data flow and typical ON-state resistance of 4Ω. |
| 5 | 1B2 | bidirectional | Multiplexer 1 channel 2 I/O port; supports rail-to-rail 0V to 5V signal levels with bidirectional data flow and typical ON-state resistance of 4Ω. |
| 6 | 1B1 | bidirectional | Multiplexer 1 channel 1 I/O port; supports rail-to-rail 0V to 5V signal levels with bidirectional data flow and typical ON-state resistance of 4Ω. |
| 7 | 1A | bidirectional | Multiplexer 1 common I/O port; connects to selected B port when 1OE is low, supporting 0V to 5V signal levels. |
| 8 | GND | power_in | Ground reference; common return for all signal and power circuits. |
| 9 | 2A | bidirectional | Multiplexer 2 common I/O port; connects to selected B port when 2OE is low, supporting 0V to 5V signal levels. |
| 10 | 2B1 | bidirectional | Multiplexer 2 channel 1 I/O port; supports rail-to-rail 0V to 5V signal levels with bidirectional data flow and typical ON-state resistance of 4Ω. |
| 11 | 2B2 | bidirectional | Multiplexer 2 channel 2 I/O port; supports rail-to-rail 0V to 5V signal levels with bidirectional data flow and typical ON-state resistance of 4Ω. |
| 12 | 2B3 | bidirectional | Multiplexer 2 channel 3 I/O port; supports rail-to-rail 0V to 5V signal levels with bidirectional data flow and typical ON-state resistance of 4Ω. |
| 13 | 2B4 | bidirectional | Multiplexer 2 channel 4 I/O port; supports rail-to-rail 0V to 5V signal levels with bidirectional data flow and typical ON-state resistance of 4Ω. |
| 14 | S0 | input | Select Pin 0 input; selects channel for each multiplexer in combination with S1 (0V to 5.5V TTL/CMOS compatible). |
| 15 | 2OE | input | Output Enable 2 Active-Low input; when low, multiplexer 2 is enabled and A port connects to selected B port (0V to 5.5V TTL/CMOS compatible). |
| 16 | VCC | power_in | Positive power supply; operating range 2.3V to 3.6V with 0.1μF bypass capacitor recommended. |
