SN74CB3T1G125DCKR from Texas Instruments, in a SC-70-5. 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 | OE | input | Active-low output enable: low turns the A-B switch ON, high gives a high-impedance state between A and B; control input accepts TTL or 5-V/3.3-V CMOS levels (VIH 1.7 V min at VCC 2.3-2.7 V, 2 V min at 2.7-3.6 V, up to 5.5 V). |
| 2 | A | bidirectional | Bidirectional switch data I/O port A, connected to B when OE is low and supporting 0- to 5.5-V signal levels. |
| 3 | GND | power_in | Ground. |
| 4 | B | bidirectional | Bidirectional switch data I/O port B, connected to A when OE is low, with output voltage translation tracking VCC and 0- to 5.5-V signal levels. |
| 5 | VCC | power_in | Supply voltage, 2.3 V to 3.6 V recommended operating range (absolute maximum 7 V). |
