SN74HCT540: ULN2803A equivalence ?

Elias NEJJARY

Part Number: SN74HCT540

Hello,

I would like to know if there is an equivalent to the ULN2803A to replace the 2 components.
My second question is as follows: can I keep only the ULN while reversing the wiring of my relays?

Hi Elias,

We don't have an equivalent device. We have 8-channel buffers but none of them will be able to match the output drive or voltage range of the ULN2803. Whether or not you can use one of our device depends entirely on the requirements of your system.

Best,

Malcolm

There is no device similar to the ULN that has inverting inputs or that sources output current.

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
