Description
SN65HVD1474DR is Texas Instruments’ high‑speed CAN transceiver. It sits between a CAN controller and the CAN bus, converting the controller’s TXD into differential CANH/CANL signals and translating bus data back to RXD. Key points:
- Supports CAN 2.0A/B at up to about 1 Mbps.
- Provides fault protection and robust automotive features (undervoltage, overcurrent/short‑to‑ground or short‑to‑VCC protection, thermal shutdown, ESD protection).
- Includes low‑power/standby mode (via STB or enable pin) for power saving.
- Operates from a typical 5 V supply (check datasheet for exact voltage range) with suitable temperature range for automotive/industrial use.
- Package: 8‑pin SOIC in a DR package (tape & reel).
Typical use: connect TXD/RXD to a CAN controller, CANH/CANL to the CAN bus, and VCC/GND to power. For exact electrical specs and pinout, consult the TI SN65HVD1474DR datasheet.

Pinout
Pin count: 14 pins (D package, SN65HVD1474DR).
Function: Dual high-speed RS-485/RS-422 transceiver (two independent channels). Each channel provides:
- DI (data input) and RO (receiver output) for TTL-compatible data
- DE (driver enable) and RE (receiver enable) per channel
- A/B differential bus pins for the RS-485/RS-422 bus
- Power/Ground pins (Vcc, GND)
In short, two differential transceiver channels in one 14‑pin package with per-channel enable control.
