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. RESET 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.
