Electrical Characteristics

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 using six sigma design limits.

2.

RESET output is active LOW for the IMP811 and RESET output is active HIGH for the IMP812.

3. Glitches of 100ns or less typically will not generate a reset pulse.
