ELECTRICAL

CHARACTERISTICS

This section provides an overview of the MTCH6301

electrical characteristics.

8.1

Absolute Maximum Ratings

Absolute maximum ratings for the MTCH6301 device

are listed below. Exposure to these maximum rating

conditions for extended periods may affect device reli-

ability. Functional operation of the device at these or

any other conditions, above the parameters indicated

in the operation listings of this specification, is not

implied.

Ambient temperature under bias …………………………………………………..................….....……..............-40 to +85°C

Storage temperature……………………………………………………………….......................…...…….………-65 to 150°C

Maximum output current sunk by any I/O pin…………………………………………………..................………………15 mA

Maximum output current sourced by any I/O pin …………………………………………………...................…………15 mA

Maximum current sunk by all ports. …………………………………………………………………….............………. 200 mA

Maximum current sourced by all ports. ………………………………………………………………………................ 200 mA

Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a

stress rating only and functional operation of the device at those or any other conditions, above those indicated in the

operation listings of this specification, is not implied. Exposure to maximum rating conditions for extended periods may

affect device reliability.
