ISL72028SEH Datasheet, PDF (6/19 Pages) Intersil Corporation – 3.3V Radiation Tolerant CAN Transceiver, 1Mbps, Low Power Shutdown, Split Termination Output

ISL72028SEH
Electrical Specifications Test Conditions: V_CC = 3.0V to 3.6V; Typicals are at T_A = +25°C (Note 7); unless otherwise specified (Note 5).
Boldface limits apply across the operating temperature range, -55°C to +125°C or over a total ionizing dose of 75krad(Si) at +25°C with exposure at a
low dose rate of <10mrad(Si)/s. (Continued)

NOTES:
5. All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless otherwise
specified.
6. Parameters with MIN and/or MAX limits are 100% tested at -55°C, +25°C and +125°C, unless otherwise specified.
7. Typical values are at 3.3V. Parameters with a single entry in the “TYP” column apply to 3.3V. Typical values shown are not guaranteed.
8. Parameter included in functional testing.
9. Performed during the 100% screening operations across the full operating temperature range. Not performed as part of TCI Group E and Group C.
Radiation characterization testing performed as part of the initial release and any major changes in design.
