Electrical Characteristics

These are stress ratings only and functional operation is not implied.

Exposure to absolute maximum ratings for prolonged time periods may

affect device reliability

Unless otherwise noted VCC is over the full voltage range, TA = –40°C to 105°C.

Typical values at TA = 25°C, VCC = 5V for L/M/J devices, VCC = 3.3V for T/S devices and VCC = 3V for R devices.

Notes:

1. Production testing done at TA = 25°C. Over-temperature specifications guaranteed by design only.

RESET output is active LOW for the IMP809 and RESET output is active HIGH for the IMP810
