TXB0106PWR 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	A1	bidirectional	Input/output 1, A-side. Referenced to VCCA (1.2V-3.6V). Auto-sensing bidirectional translator channel; internal ~4kΩ one-shot drivers require external pull resistors > 50kΩ if any are used.
2	VCCA	power_in	A-port supply voltage. 1.2V ≤ VCCA ≤ 3.6V; must satisfy VCCA ≤ VCCB. Sets logic levels for all A-side I/Os and the OE input; place a local decoupling capacitor to GND.
3	A2	bidirectional	Input/output 2, A-side. Referenced to VCCA (1.2V-3.6V). Auto-sensing bidirectional translator channel.
4	A3	bidirectional	Input/output 3, A-side. Referenced to VCCA (1.2V-3.6V). Auto-sensing bidirectional translator channel.
5	A4	bidirectional	Input/output 4, A-side. Referenced to VCCA (1.2V-3.6V). Auto-sensing bidirectional translator channel.
6	A5	bidirectional	Input/output 5, A-side. Referenced to VCCA (1.2V-3.6V). Auto-sensing bidirectional translator channel.
7	A6	bidirectional	Input/output 6, A-side. Referenced to VCCA (1.2V-3.6V). Auto-sensing bidirectional translator channel.
8	OE	input	Output enable, active high. Pull OE low to place all A and B outputs in high-impedance state. Input circuit is referenced to VCCA; tie to GND via a pull-down resistor to force high-Z during power-up/down.
9	GND	power_in	Device ground reference.
10	B6	bidirectional	Input/output 6, B-side. Referenced to VCCB (1.65V-5.5V). Auto-sensing bidirectional translator channel; ±15kV HBM ESD protected.
11	B5	bidirectional	Input/output 5, B-side. Referenced to VCCB (1.65V-5.5V). Auto-sensing bidirectional translator channel; ±15kV HBM ESD protected.
12	B4	bidirectional	Input/output 4, B-side. Referenced to VCCB (1.65V-5.5V). Auto-sensing bidirectional translator channel; ±15kV HBM ESD protected.
13	B3	bidirectional	Input/output 3, B-side. Referenced to VCCB (1.65V-5.5V). Auto-sensing bidirectional translator channel; ±15kV HBM ESD protected.
14	B2	bidirectional	Input/output 2, B-side. Referenced to VCCB (1.65V-5.5V). Auto-sensing bidirectional translator channel; ±15kV HBM ESD protected.
15	VCCB	power_in	B-port supply voltage. 1.65V ≤ VCCB ≤ 5.5V; must satisfy VCCB ≥ VCCA. Sets logic levels for all B-side I/Os; place a local decoupling capacitor to GND.
16	B1	bidirectional	Input/output 1, B-side. Referenced to VCCB (1.65V-5.5V). Auto-sensing bidirectional translator channel; ±15kV HBM ESD protected.
