Description

1

VDD1

Power Supply (Logic Side).

2, 7, 8

GND1

Ground (Logic Side).

3

RxD

Receiver Output Data. When enabled, if (A − B) ≥ −30 mV, then RxD = high; if (A − B) ≤ −200 mV, then

RxD = low. This is a tristate output when the receiver is disabled, that is, when RE is driven high.

4

RE

Receiver Enable Input. This is an active-low input. Driving this input low enables the receiver, and

driving it high disables the receiver.

5

DE

Driver Enable Input. Driving the input high enables the driver, and driving it low disables the driver.

6

TxD

Transmit Data Input. Data to be transmitted by the driver is applied to this input.

9, 10, 15

GND2

Ground (Bus Side).

11, 14

NC

No Connect.

12

A

Noninverting Driver Output/Receiver Input. When the driver is disabled, or when VDD1 or VDD2 is

powered down, Pin A is put into a high impedance state to avoid overloading the bus.

13

B

Inverting Driver Output/Receiver Input. When the driver is disabled, or when VDD1 or VDD2 is powered

down, Pin B is put into a high impedance state to avoid overloading the bus.

16

VDD2

Power Supply (Bus Side).
