Descripción general

Description

SN65HVD77DR is Texas Instruments’ RS-485/RS-422 transceiver. It provides half-duplex differential signaling with a driver (DI) and receiver (RO) and bus pins (A, B). Control pins DE (driver enable) and RE (receiver enable) govern transmission and reception. It supports RS-485/RS-422 multi-drop networks at data rates up to about 5 Mbps. The receiver isFail-Safe, producing a logic-high RO when the bus is idle or faulted. It operates from a single supply (typical 3.0–5.5 V) and is designed for rugged industrial/automation environments, with robust ESD protection and small 8-pin packaging. The DR suffix indicates the specific packaging for this device.

Package

SN65HVD77DR uses an 8‑pin SOIC (D‑package) with Tape‑and‑Reel packaging.

Pinout

- Pin count: 8 pins (8-pin package such as SOIC/VSSOP).
- Function: High-speed CAN transceiver. Interfaces a CAN controller to the CAN bus: TXD input and RXD output on the logic side, CANH/CANL on the bus side, plus VCC, GND, and standby/enable pins.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI)
- What kind of company: An American multinational technology company that designs and manufactures semiconductors, notably analog and embedded processing ICs. It is one of the world's largest semiconductor producers.

Application

SN65HVD77DR is a differential RS-485/RS-422 half-duplex transceiver. Common application areas: industrial automation and PLC I/O networks; building automation (HVAC, lighting, security); process control and instrumentation; data acquisition and remote sensors; energy metering and smart-grid interfaces; Modbus/RS-485 multi-point networks. It supports robust, long-distance communication in harsh industrial environments.
