Keysight Agilent HP 44474A Features:
- 16-Bit TTL Compatible Digital I/O
- Input/Output Re-configurable byte-by-byte
The Keysight Agilent HP 44474A provides 16 bi-directional data lines (bits) plus 4 lines used for control and handshaking. All lines are TTL compatible. The 16 data lines offer 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. For instance, one port can be used for output operation, while the other for input. Each I/O line can sink current up to 0.125A from external devices.
