Agilent N2263A

• TTL compatible, sinking up

to 0.6 A

• Input /output configurable

byte-by-byte

• Three I/O control modes:

static, strobe, and handshake

The N2263A provides 32-bit bi-

directional lines and three hand-

shake and control lines. The 32-bit

I/O lines are TTL compatible

input/output, or TTL compatible

input and open collector output

up to 42 V. The 32-bit I/O lines can

be addressed individually (byte-

by-byte), either as a 32-bit port,

four independent 8-bit ports, or

as two independent 16-bit ports.

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.

The screw terminal block and

DIN96-to-Twin-D50 cable are

available for simple wiring .
