SN74CBT3306CDR from Texas Instruments, in a SOIC-8. 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 | 1OE | input | Output Enable for switch 1, active low; connects 1A to 1B when low (≤0.8 V), high-impedance disconnect when high (≥2 V) |
| 2 | 1A | bidirectional | Bidirectional data port A for switch 1; supports signal flow (0 to 5.5 V) through low-resistance FET switch when 1OE is low |
| 3 | 1B | bidirectional | Bidirectional data port B for switch 1; supports signal flow (0 to 5.5 V) through low-resistance FET switch when 1OE is low |
| 4 | GND | power_in | Ground reference voltage |
| 5 | 2A | bidirectional | Bidirectional data port A for switch 2; supports signal flow (0 to 5.5 V) through low-resistance FET switch when 2OE is low |
| 6 | 2B | bidirectional | Bidirectional data port B for switch 2; supports signal flow (0 to 5.5 V) through low-resistance FET switch when 2OE is low |
| 7 | 2OE | input | Output Enable for switch 2, active low; connects 2A to 2B when low (≤0.8 V), high-impedance disconnect when high (≥2 V) |
| 8 | VCC | power_in | Positive supply voltage; 4 V to 5.5 V recommended operating range |
