2 A0 tri_state A bus line 1 bidirectional buffer with tri-state output
3 A1 tri_state A bus line 2 bidirectional buffer with tri-state output
4 A2 tri_state A bus line 3 bidirectional buffer with tri-state output
5 A3 tri_state A bus line 4 bidirectional buffer with tri-state output
6 A4 tri_state A bus line 5 bidirectional buffer with tri-state output
7 A5 tri_state A bus line 6 bidirectional buffer with tri-state output
8 A6 tri_state A bus line 7 bidirectional buffer with tri-state output
9 A7 tri_state A bus line 8 bidirectional buffer with tri-state output
10 GND power_in Ground reference connection
11 B7 tri_state B bus line 8 bidirectional buffer with tri-state output
12 B6 tri_state B bus line 7 bidirectional buffer with tri-state output
13 B5 tri_state B bus line 6 bidirectional buffer with tri-state output
14 B4 tri_state B bus line 5 bidirectional buffer with tri-state output
15 B3 tri_state B bus line 4 bidirectional buffer with tri-state output
16 B2 tri_state B bus line 3 bidirectional buffer with tri-state output
17 B1 tri_state B bus line 2 bidirectional buffer with tri-state output
18 B0 tri_state B bus line 1 bidirectional buffer with tri-state output
19 OE input Output enable input, active low; when high, all outputs placed in high-impedance state
20 VCC power_in Power supply voltage 1.5V to 5.5V for AC type, 4.5V to 5.5V for ACT type
