When it says a 5V relay or 5V coil, what exactly does that 5V mean? Is that the max voltage that can be applied to the coil before its damaged?The datasheet for the relay shows four 5V coils. One is 50 ohms so its current is 5V/50 ohms= 100mA. Another coil is 167 ohms so its current is 5V/167 ohms= 30mA.
An LM339 is made to drive low current electronic circuits not a high current mecahnical relay.
Aha! I didn't notice that they had a .PDF version of the data sheet. The .PDF version makes it clear that they have a variety of relays with different coil current requirements. The most sensitive version, as Audioguru points out, requires 30 mA which is beyond the rating of the LM339.The datasheet for the relay shows four 5V coils. One is 50 ohms so its current is 5V/50 ohms= 100mA. Another coil is 167 ohms so its current is 5V/167 ohms= 30mA.
