It translates logic levels from one supply to another, making it suitable for interfacing legacy 5 V logic with lower-voltage 3.3 V or 2.5 V cores, or for bidirectional bus isolation. The part is a standard HEF4104BT variant with a specific ordering code, carrying an active lifecycle status for ongoing production support. The active status also means standard lead times apply through distribution channels, with no premium for end-of-life inventory. ## Bulk packaging for prototyping and low-volume runs Bulk units are easier to handle for manual assembly and rework, though for high-volume automated lines a tape-and-reel variant of the HEF4104BT family may be more efficient. The Bulk format does not affect electrical performance or pinout.","metaTitle":"HEF4104BT/S400118 Bus Driver, 4-Bit, Active - NXP","metaDescription":"NXP HEF4104BT/S400118 is a 4-bit bus driver for level-shifting applications.

It is functionally identical in terms of logic and level-shifting capability; the difference is in the packaging format (Bulk) and ordering code. It is a direct functional replacement for any standard HEF4104BT in the same package."},{"question":"Can HEF4104BT be used for 3.3V to 5V level shifting?","answer":"Yes, the HEF4104BT is a 4-bit bus driver specifically designed for level translation between different voltage domains, including 3.3 V to 5 V and vice versa.
