N74F257ADR Datasheet No te. Even if the thermo-elecVic cooler (TEC) is operated within the rate d conditions, unconVolled current loading or operation without heatsink may easily damage the mod ule by exceeding the storage temperature range. Th errnistor resistan ce should be properly monitored by the feedback crcuit during TE C operation to avoid the catastrophic damage.
