2017 PGM T5.1

DC ELECTRICAL CHARACTERISTICS VDD = 2.7V to 5.5V, VH = VDD, VL = 0V, Unless otherwise

specified

Notes:

1. IDD is the supply current drawn while the EEPROM is being updated. IDD does not include the current that flows through the Reference

resistor chain.

2. UP# and DWN# have internal pull-up resistors of approximately 50k

Ω. When the input is pulled to ground the resulting output current

will be VDD/50ký.
