SN74LVTH16245ADGVR

The Texas Instruments SN74LVTH16245ADGVR is a 16-bit non-inverting bus transceiver from the LVT (low-voltage BiCMOS technology) family, designed with 3-state outputs for bidirectional data flow in 3.3 V systems.

Operating from a nominal 3.3 V supply, this device provides high-current bus drive while maintaining compatibility with 5 V logic levels on all I/O ports and control inputs, enabling mixed-voltage interfacing without external level translators. Internal circuitry supports live insertion and partial-power-down operation (Ioff) to prevent damaging backdrive current when the device is unpowered. The 48-pin TVSOP package (DGVR suffix) offers compact footprint and low profile, well-suited for high-density PCB layouts where board real estate is constrained. Typical propagation delays and output drive align with the LVT family’s balance of speed and power efficiency, making the transceiver effective in high-speed data paths, backplane communication, and memory address driving. Applications span industrial automation, telecom infrastructure, networking equipment, and ruggedized computing environments where dependable bus isolation and signal integrity are critical.

Procurement professionals evaluating this component should note that the SN74LVTH16245ADGVR is a commercial-temperature-grade device (0°C to 70°C) as indicated by the SN prefix; variants with industrial or military temperature ranges carry different prefixes or suffixes. As a mature standard-logic product actively supported by Texas Instruments, long-term availability is generally stable, but design cycles in high-reliability sectors warrant verification of roadmap status and authorized distribution channels. Authentic traceability, electrostatic discharge sensitivity, and proper handling requirements typical of CMOS logic should be factored into supply chain planning.
