SN74LVTH16244ADGVR

The SN74LVTH16244ADGVR is a 16-bit buffer/driver with 3-state outputs manufactured by Texas Instruments, part of the LVTH family of low-voltage (3.3 V) advanced BiCMOS bus-interface logic. This device integrates four 4-bit buffer sections with independent output-enable controls, enabling flexible byte‑wide or word‑wide interfacing. Key features include 5 V tolerant inputs and outputs for direct connection to legacy 5 V systems, bus‑hold circuitry on all data inputs that eliminates external pull‑up resistors, and Ioff circuitry supporting live insertion and partial‑power‑down protection. The high‑drive output stage typically sources 32 mA and sinks 64 mA, satisfying the requirements of heavily loaded data buses and backplanes.

Typical applications span industrial automation, network and telecom infrastructure, server backplane driving, and memory address buffering, where robust mixed‑voltage signal translation and bus isolation are essential. In aerospace and defense subsystems, the device’s live‑insertion capability and bus‑hold simplify design of redundant architectures and line‑replaceable units. Procurement engineers should note that this part is supplied in an SSOP package and operates over the commercial temperature range (0°C to 70°C). Texas Instruments maintains long‑term supply of its LVTH logic portfolio, but for programs demanding extended temperature or MIL‑PRF‑38535 qualification, the SN54LVTH16244A equivalent is the recommended alternate. Standard ESD and latch‑up protection align with industrial handling requirements.
