SN754410: Heat dissipation, power capability.

Part Number: SN754410

I am designing a product which will use two SN754410 bridge drivers. I have followed the pcb layout recommendations for heat transfer, but would it be acceptable to have them in DIL sockets? i.e would enough heat transfer through the pins of a DIL socket?

Cheers, Moby.

    Maurice,

    That's a good question. The socket will change the thermal performance.

    May I assume you mean  "DIP socket" ?

    I would expect the ZIF and leaf pin sockets would be worse than machined pin sockets.

    See if the socket provider can provide thermal resistance values.
