SN75ALS1178NSR

SN75ALS1178NSR is a Texas Instruments device in the SN75ALS family. It is a high-speed, low-power bus transceiver/buffer used to transfer data between two separate buses. It provides bidirectional data flow, typically via a direction control input and an output-enable (tri-state) control so that either side can drive the other while the outputs can be disabled to isolate buses. The NSR suffix denotes a RoHS-compliant package option.
Key points:
- Purpose: buffer/translate data between two buses, enabling bus isolation and expansion.
- Topology: bidirectional transceiver with enable and direction control.
- Applications: microprocessor interfaces, backplanes, peripheral interconnects, and other one-to-many bus architectures requiring fast data transfer with minimal loading.
- Packaging: RoHS-compliant TI package (NSR variant); consult datasheet for exact pinout.
Note: For exact electrical specifications (voltage range, clocking (if any), timing, and pinout), refer to the TI SN75ALS1178 datasheet. If you have a specific application, I can help map the requirements to the datasheet parameters.

8-pin small‑outline package (SOIC). The NSR suffix identifies the RoHS‑compliant SOIC variant.

Pin count: 16 pins (NSR package).
Function: SN75ALS1178NSR is a high-speed differential line transceiver for RS-485/RS-422 style communications (single-channel), providing a driver and receiver with enable controls for bidirectional data on a differential pair.

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational electronics company that designs and manufactures semiconductors and integrated circuits (analog, digital, embedded processing, sensors, etc.).

SN75ALS1178NSR is a high-speed differential line transceiver for balanced data signaling. Applications include backplane and board-to-board interconnects, high-speed serial links (LVDS-style data paths), and RS-485/422-like networks in industrial, telecom, and automotive systems requiring low noise and good EMI performance.
