Not for a motor drive cabinet or an outdoor telecom enclosure where the temperature swings below freezing. ## Package and mounting — surface-mount SOIC, reworkable No thermal pad, no hidden leads — you can swap it with a hot-air station if the board comes back for repair. The supplier device package is 20-SOIC, so the footprint matches any standard SOIC-20 land pattern.","metaTitle":"SN74LS245DW 74LS Transceiver, Non-Inverting, 20-SOIC","metaDescription":"SN74LS245DW 8-bit 3-state bus transceiver, 4.75V-5.25V supply, 15/24 mA drive, 0°C to 70°C.
