Description

Input

Schmitt-triggered input

Output with 2 mA sink and 2 mA source

OD2

Open-drain output with 2 mA sink and 2 mA source

Output with 8 mA sink and 8 mA source

200kΩ (typical) internal pull-down.

Note:

Internal pull-down resistors prevent unconnected inputs from floating. Do not rely

on internal resistors to drive signals external to the device. When connected to a

load that must be pulled low, an external resistor must be added.

Analog input

Analog output

AIO

Analog bidirectional

Power pin

Note:

Refer to Section 5.5, "DC Characteristics," on page 28 for the electrical characteristics of the various buf-

fers.
