Hp 44474A digital i/o module w/ cable block
Up for sale is a HP 44474A Digital I/O module. It provides 16 bi-directional TTL compatible data lines (bits) plus 4 lines used for control and handshaking. The 16 data lines have TTL compatible input and open collector output. The 16 I/O lines or bits can be addressed individually (bit-by-bit), or as two independent 8-bit ports, or as one 16-bit word. Each I/O line can sink current up to 0.125A from external devices.
We have a number of 60 pcs for sale. Individual testing extends to power-up the card in a HP3488A mainframe and seeing the self-test to pass.
