Product details

The SN74AHCT244NSR: Two elements each handle four bits with 8mA source and sink per output.

The 125°C ceiling means it can sit next to a hot processor or power stage without derating the output drive.

The 20-SOIC body (0.209" wide, 5.30 mm) has a 1.27 mm lead pitch — a standard profile that hot-air stations and soldering irons handle comfortably. The leads are gull-wing, which makes visual inspection of solder joints easy.

The 74AHCT family is mature and widely second-sourced, though TI's own 74AHCT line is the primary reference.
