SN74AVC8T245PWR from Texas Instruments, in a TSSOP-24. 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 VCCA power_in A-port supply voltage. 1.2 V ≤ VCCA ≤ 3.6 V. Also supplies the DIR and OE control inputs.
2 DIR input Direction-control signal. High selects A→B, low selects B→A. Referenced to VCCA.
3 A1 bidirectional Input/output A1. Referenced to VCCA (1.2 V to 3.6 V).
4 A2 bidirectional Input/output A2. Referenced to VCCA (1.2 V to 3.6 V).
5 A3 bidirectional Input/output A3. Referenced to VCCA (1.2 V to 3.6 V).
6 A4 bidirectional Input/output A4. Referenced to VCCA (1.2 V to 3.6 V).
7 A5 bidirectional Input/output A5. Referenced to VCCA (1.2 V to 3.6 V).
8 A6 bidirectional Input/output A6. Referenced to VCCA (1.2 V to 3.6 V).
9 A7 bidirectional Input/output A7. Referenced to VCCA (1.2 V to 3.6 V).
10 A8 bidirectional Input/output A8. Referenced to VCCA (1.2 V to 3.6 V).
11 GND power_in Ground reference.
12 GND power_in Ground reference.
13 GND power_in Ground reference.
14 B8 bidirectional Input/output B8. Referenced to VCCB (1.2 V to 3.6 V).
15 B7 bidirectional Input/output B7. Referenced to VCCB (1.2 V to 3.6 V).
16 B6 bidirectional Input/output B6. Referenced to VCCB (1.2 V to 3.6 V).
17 B5 bidirectional Input/output B5. Referenced to VCCB (1.2 V to 3.6 V).
18 B4 bidirectional Input/output B4. Referenced to VCCB (1.2 V to 3.6 V).
19 B3 bidirectional Input/output B3. Referenced to VCCB (1.2 V to 3.6 V).
20 B2 bidirectional Input/output B2. Referenced to VCCB (1.2 V to 3.6 V).
21 B1 bidirectional Input/output B1. Referenced to VCCB (1.2 V to 3.6 V).
22 OE input 3-state output-mode enable (active low). Pull OE high to place all outputs in the high-impedance state. Referenced to VCCA.
23 VCCB power_in B-port supply voltage. 1.2 V ≤ VCCB ≤ 3.6 V.
24 VCCB power_in B-port supply voltage. 1.2 V ≤ VCCB ≤ 3.6 V.
