Visão Geral
Description
The SN751177NSR is a Texas Instruments device in the SN7511x family. It’s an 8-bit data-register/buffer with tri-state outputs used to drive or buffer a data bus. It latches 8-bit input on a clock edge and can place its 8 outputs in a high‑impedance state via an enable control, making it suitable for microprocessor data-bus buffering and peripheral registers. The NSR suffix denotes the package style (Narrow SOIC, etc.). For exact pinout, timing, and electrical specs, consult the SN751177 datasheet on TI’s site. If you want, I can pull out the key pins and timing diagrams.
