Additional Features: 

• 32-bit bidirectional lines
• 3 handshake and control lines
• TTL compatible,sinking up to 0.6 A, 42V
• address 32 I/O lines individually, as two 16-bit ports or as four independent 8-bit ports
• Input /Output configurable byte-by-byte
• Three I/O control modes: static, strobe and handshake

The Agilent N2263A is a 32-bit digital I/O module. It provides 32-bit bi-directional lines and three handshake and control lines. The 32-bit I/O lines are TTL compatible input/output, or TTL compatible input and open collector output up to 42V. A Zener diode is used in each channel for input voltage over-protection (>42 VDC), including ESD protection. Each I/O line can sink up to 0.6 A to control external devices including:

• High voltage/high current relays;
• Microwave relays and attenuators (8710xx , 876xx and 849xx);
• Solenoid coils

The polarities of the I/O and handshake lines can be operated in positive or negative logic mode. With the three control lines (PCTL, I/O and PFLG), you can define five handshake modes for communication with peripherals.
