Product Description:
The Tektronix VX4801 offers 48 optical isolated TTL or CMOS-compatible bidirectional digital I/O lines. The 48 programmable I/O signal lines are organized into six 8-bit bytes. Each of these 6 bytes can be configured independently under full program control. Under program control, the input, output and handshake line induction can be set to high or low level active. All I/O lines are compatible with TTL and CMOS, providing up to 24mA of absorbed current per output.
