This datasheet introduces the features and characteristics of 74LVT16245 and 74LVTH16245 16-bit low voltage tri-state output bidirectional buffers, including general description, input and output control, and application recommendations.
The 74LVT16245 and 74LVTH16245 are 16‑bit, non‑inverting bidirectional buffers with 3‑state outputs. Each byte is independently controlled, and the control pins can be shorted together for full‑width operation. The devices support bus‑hold inputs (LVTH version) and provide high‑current source/sink capability.
The datasheet lists three package families—FBGA 54‑ball (BGA54A), SSOP 48‑lead (MS48A), and TSSOP 48‑lead (MTD48)—with detailed mechanical dimensions. Electrical characteristics include supply voltage ranges, input‑output voltage thresholds, output drive currents, and temperature limits. Ordering codes and life‑support policy notes are also provided.
