2 O0 tri_state Data output 0 with 64-mA sink current and 32-mA source current.
3 D0 input Data input 0, captured on rising edge of CP with 2-ns setup time.
4 D1 input Data input 1, captured on rising edge of CP with 2-ns setup time.
5 O1 tri_state Data output 1 with 64-mA sink current and 32-mA source current.
6 O2 tri_state Data output 2 with 64-mA sink current and 32-mA source current.
7 D2 input Data input 2, captured on rising edge of CP with 2-ns setup time.
8 D3 input Data input 3, captured on rising edge of CP with 2-ns setup time.
9 O3 tri_state Data output 3 with 64-mA sink current and 32-mA source current.
10 GND power_in Ground, logic reference potential.
11 CP input Clock input, buffered clock pulse with low-to-high transition capturing D inputs.
12 O4 tri_state Data output 4 with 64-mA sink current and 32-mA source current.
13 D4 input Data input 4, captured on rising edge of CP with 2-ns setup time.
14 D5 input Data input 5, captured on rising edge of CP with 2-ns setup time.
15 O5 tri_state Data output 5 with 64-mA sink current and 32-mA source current.
16 O6 tri_state Data output 6 with 64-mA sink current and 32-mA source current.
17 D6 input Data input 6, captured on rising edge of CP with 2-ns setup time.
18 D7 input Data input 7, captured on rising edge of CP with 2-ns setup time.
19 O7 tri_state Data output 7 with 64-mA sink current and 32-mA source current.
20 VCC power_in Supply voltage 4.75 to 5.25 V.
