Configuring the Agilent E1330B Digital I/O Module 29

Chapter 2

Typical Connection

Figure 2-11 shows a typical driver/receiver connection for data transfer.

The FLG, PIR, and STS lines have a discrete resistive pull-up network. The

data lines do not have a discrete resistive pull-up, but can use an internal

pull-up in the 75ALS160. The internal pull-up requires that the data lines

sink 3.2 mA to pull the line to less than 0.4 V. The I/O

, CTL, and RES lines

are open collector, and require external pull-up to logic high.
