2 DIR input Direction control input; logic high selects A-to-B transfer, logic low selects B-to-A transfer.
3 A1 bidirectional Port A bidirectional data I/O channel 1, operating 0V to VCCA.
4 A2 bidirectional Port A bidirectional data I/O channel 2, operating 0V to VCCA.
5 A3 bidirectional Port A bidirectional data I/O channel 3, operating 0V to VCCA.
6 A4 bidirectional Port A bidirectional data I/O channel 4, operating 0V to VCCA.
7 A5 bidirectional Port A bidirectional data I/O channel 5, operating 0V to VCCA.
8 A6 bidirectional Port A bidirectional data I/O channel 6, operating 0V to VCCA.
9 A7 bidirectional Port A bidirectional data I/O channel 7, operating 0V to VCCA.
10 A8 bidirectional Port A bidirectional data I/O channel 8, operating 0V to VCCA.
11 GND power_in Ground reference.
12 GND power_in Ground reference.
13 GND power_in Ground reference.
14 B8 bidirectional Port B bidirectional data I/O channel 8, operating 0V to VCCB.
15 B7 bidirectional Port B bidirectional data I/O channel 7, operating 0V to VCCB.
16 B6 bidirectional Port B bidirectional data I/O channel 6, operating 0V to VCCB.
17 B5 bidirectional Port B bidirectional data I/O channel 5, operating 0V to VCCB.
18 B4 bidirectional Port B bidirectional data I/O channel 4, operating 0V to VCCB.
19 B3 bidirectional Port B bidirectional data I/O channel 3, operating 0V to VCCB.
20 B2 bidirectional Port B bidirectional data I/O channel 2, operating 0V to VCCB.
21 B1 bidirectional Port B bidirectional data I/O channel 1, operating 0V to VCCB.
22 OE input Output enable input, active low; logic high disables all outputs to high-impedance state.
23 NC unconnected No internal connection.
24 VCCB power_in Power supply for port B, operating range 3V to 5.5V.
