Name

Description

1

RO

Receiver Output: When DE/RE* (Receiver Enable) is LOW, the receiver is enabled (ON), if DO/RI

≥

DO*/RI* by 200 mV, RO will be HIGH. If DO/RI

≤ DO*/RI* by 200 mV, RO will be LOW. Additionally RO

will be HIGH for OPEN (Non-terminated) inputs.

2

SR

Slew Rate Control: A resistor connected to Ground controls the Driver Output rising and falling edge

rates.

3

DE/RE*

Combined Driver and Receiver Output Enable: When signal is LOW the receiver output is enabled and

the driver outputs are in TRI-STATE (OFF). When signaI is HlGH, the receiver output is in TRI-STATE

(OFF) and the driver outputs are enabled.

4

DI

Driver Input: When DE/RE* is HlGH, the driver is enabled, if DI is LOW, then DO/RI will be LOW and

DO*/RI* will be HIGH. If DI is HIGH, then DO/RI is HIGH and DO*/RI* is LOW.
