The P6406 uses the P64xx-family 10-wire input lead harnesses with 0.2" connectors. Is also possible to use standard jumper wires with pins, sockets or clips on the other end for connecting inputs.

Internals

The 16 inputs connect (via 330 Ω resistors) to inputs of four 74LS266 quad exclusive-NOR gates that receive bit-inversion masks from two of three 74LS164 serial-in, parallel-out shift registers. The third shift register provides don't care masks (one per group of four inputs). After the logic circuits, a 74S140 cable driver sends the trigger signal to the 308.
