4 / 19 page +3.3V/+5V, 8-Channel Relay Drivers with Fast Recovery Time and Power-Save Mode 4 _______________________________________________________________________________________ Note 1: Specifications at -40°C are guaranteed by design and not production tested. Note 2: Thermal shutdown disables power save from all channels to reduce power dissipation inside the device. Note 3: Thermal shutdown turns off all channels. Note 4: The circuit can set the output voltage in power-save mode only if IOUT x RON < VOUTP. Note 5: After relay turn-off, inductive kickback can momentarily cause the OUT_ voltage to exceed VCC. This is considered part of normal operation and does not damage the device. Note 6: Guaranteed by design. Note 7: For other capacitance values, use the equation tPS = 32 x C. ELECTRICAL CHARACTERISTICS (continued) (VCC = +2.7V to +5.5V, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VCC = 2.7V, TA = +25°C, unless otherwise noted.)
