Note 2: All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to ground unless otherwise specified. Note 3: Guaranteed by design, not subject to test. Note 4: Values referred to VILD and VIHD. Note 5: A Zener diode clamps the relay drivers at 18V (RELAY 1-4). |
