Pin Description
PIN
NAME
FUNCTION
1
RO
Receiver Output
2
RE
Receiver Output Enable. RO is enabled when RE is low; RO is high impedance when RE is high. The
device enters a low-power shutdown mode if RE is high and DE is low.
3DE
Driver Output Enable. Driving DE high enables the driver outputs. Pulling DE low puts the driver
outputs in a high-impedance state. If RE is high and DE is low, the device enters a low-power
shutdown mode. If the driver outputs are enabled, the device functions as a line driver, and when
they are high impedance it functions as a line receiver if RE is low.
4DI
Driver Input. A logic low on DI forces output A low and output B high, while a logic high on DI forces
output A high and output B low.
5
GND
Ground
6
A
Noninverting Receiver Input/Driver Output
7
B
Inverting Receiver Input/Driver Output
8VCC
Positive Supply, VCC = +3.3V ±10%. Bypass VCC to GND with a 0.1F ceramic capacitor.
