74LVC2T45DC from Nexperia, in a VSSOP-8-0.5mm. 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	VCC(A)	power_in	Supply voltage for port A and DIR input. Operating range 1.2 V to 5.5 V (abs max 6.5 V). When VCC(A) is at GND the device enters suspend mode with A and B in high-impedance OFF-state.
2	1A	bidirectional	Port A bit 1 data input or output, referenced to VCC(A). Direction set by DIR: when DIR = HIGH, 1A is an input and drives 1B; when DIR = LOW, 1A is an output driven by 1B. High-Z in suspend or 3-state mode.
3	2A	bidirectional	Port A bit 2 data input or output, referenced to VCC(A). Direction set by DIR: when DIR = HIGH, 2A is an input and drives 2B; when DIR = LOW, 2A is an output driven by 2B. High-Z in suspend or 3-state mode.
4	GND	power_in	Ground reference (0 V) for both supply domains.
5	DIR	input	Direction control input, referenced to VCC(A). HIGH selects transmission from nA to nB; LOW selects transmission from nB to nA. Input accepts voltages up to 5.5 V regardless of VCC(A).
6	2B	bidirectional	Port B bit 2 data input or output, referenced to VCC(B). Direction set by DIR: when DIR = LOW, 2B is an input and drives 2A; when DIR = HIGH, 2B is an output driven by 2A. High-Z in suspend or 3-state mode.
7	1B	bidirectional	Port B bit 1 data input or output, referenced to VCC(B). Direction set by DIR: when DIR = LOW, 1B is an input and drives 1A; when DIR = HIGH, 1B is an output driven by 1A. High-Z in suspend or 3-state mode.
8	VCC(B)	power_in	Supply voltage for port B. Operating range 1.2 V to 5.5 V (abs max 6.5 V), independent of VCC(A) so the part translates between any two rails in that range. When VCC(B) is at GND the device enters suspend mode with A and B in high-impedance OFF-state.
