ISO7221C-HT

SLLSE78

– APRIL 2011

www.ti.com

This device requires two supply voltages of 3.3 V, 5 V, or any combination. All inputs are 5-V tolerant when

supplied from a 3.3-V supply and all outputs are 4-mA CMOS.

The ISO7221 is characterized for operation over the ambient temperature range of

–55°C to 175°C.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings

only and functional operation of the device at these or any other conditions beyond those indicated under recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
