SN74LVTH16245ADGGR

The Texas Instruments SN74LVTH16245ADGGR is a 16-bit bus transceiver with 3-state outputs, belonging to the low-voltage BiCMOS LVT family and engineered for high-performance data-path management in 3.3V systems. This device incorporates integrated bus-hold circuitry on data I/O pins, which eliminates the need for external pull-up resistors and prevents floating inputs during live insertion or power sequencing. It operates from a single 3.3V supply while providing 5V-tolerant inputs, allowing direct interface with legacy 5V logic without level-shifting components. The outputs feature high-current drive capability characteristic of the LVT family, supporting heavily loaded backplanes and minimizing signal reflections in transmission-line environments. The 16-bit bidirectional data flow with configurable direction control makes it suitable for wide bus structures where signal integrity and low ground bounce are critical.

Typical end-use scenarios include industrial automation controllers, telecom switching backplanes, server memory buses, and ruggedized networking equipment where high-speed parallel data transfer across long traces must be maintained with minimal propagation delay. In aerospace and defense subsystems, the device’s ability to withstand hot-swap events and latch-up immunity supports high-reliability mission-critical designs. From a procurement perspective, the SN74LVTH16245ADGGR is supplied in a TSSOP surface-mount package in tape-and-reel format, meeting commercial/industrial temperature grades common for this logic family. Design and supply-chain engineers should verify long-term lifecycle status with authorized distribution to mitigate end-of-life risk, particularly for sustained production runs in regulated industries where part-number changes can trigger requalification overhead.
