DC PARAMETERS
MAXIMUM GUARANTEED RATINGS
Operating Temperature Range ...........................................................................................................................0oC to +70oC
Storage Temperature Range ........................................................................................................................... -55o to +150oC
Lead Temperature Range (soldering, 10 seconds).....................................................................................................+325oC
Positive Voltage on any pin, with respect to Ground (Note 1)...................................................................................Vcc+0.3V
Negative Voltage on any pin, with respect to Ground .................................................................................................... -0.3V
Maximum Vcc .................................................................................................................................................................. +3.6V
Note 1: Maximum voltage on all I type Inputs and the IS inputs, OD12 and OD24 outputs for floppy disk drive interface is
5.25V
*Stresses above the specified parameters could cause permanent damage to the device. This is a stress rating only
and functional operation of the device at any other condition above those indicated in the operation sections of this
specification is not implied.
Note 2: When powering this device from laboratory or system power supplies, it is important that the Absolute Maximum
Ratings not be exceeded or device failure can result. Some power supplies exhibit voltage spikes on their outputs when
the AC power is switched on or off. In addition, voltage transients on the AC power line may appear on the DC output.
When this possibility exists, it is suggested that a clamp circuit be used.
