概述

Description

The SN751177NSR is a Texas Instruments TTL logic IC in the SN7511x family. It is a 4-bit register/luffer-type device used to latch and buffer data on a bus or between digital blocks. Key idea: it takes four D inputs, captures them on a clock edge, and presents four Q outputs, typically with a tri-state/enable option to allow bus sharing. It runs from a standard 5 V supply (TTL logic levels) and is packaged in an NSR variant (a TI small-outline/DIP-style package with RoHS-compliant options).
Common uses include buffering and temporary data storage in microprocessor/muscle bus interfaces, data latching in timing-critical circuits, and front-end data staging before further processing.
For exact pinout, timing, enable behavior, and electrical specs (voltage, current, setup/hold times), consult the TI SN751177NSR datasheet and the package drawing. If you have a specific application, I can map the pins and suggest usage.

Package

Plastic Small-Outline package (SOIC), 20 pins. “NSR” is TI’s suffix for this surface-mount package.

Pinout

- Pin count: 16 pins (NSR indicates a SOIC-16 package).
- Function: Quad 2-input data selector (multiplexer) with a common select input (four 2:1 multiplexers).

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: TI is an American multinational corporation that designs and manufactures semiconductors and integrated circuits for a wide range of applications.

Application

Application areas of SN751177NSR:
- Buffering address/data lines between microprocessors and memory/peripherals
- Bus interfacing and bus-expansion in digital systems
- Tri-state buffering/driving for shared buses
- Signal conditioning in embedded, industrial, and communication interfaces
- TTL-compatible data paths in consumer electronics and related systems
