SN65HVD3088EDGKR

The SN65HVD3088EDGKR is a Texas Instruments high‑speed, half‑duplex RS-485/RS-422 transceiver. It sits between a microcontroller’s TTL/CMOS logic and a two‑wire differential RS‑485 bus, enabling two‑way, multi‑point industrial communication on a single pair of wires.
Key points:
- Drives and detects differential A/B signals for RS‑485/RS‑422 networks.
- Half‑duplex with driver enable (DE) and receiver enable (/RE) controls for direction.
- Failsafe receiver output: guarantees a valid logic level on RO when inputs are idle/open/shorted.
- Compact 8‑pin package; wide supply range; designed for robust industrial environments (short‑circuit protection, ESD tolerance in typical TI transceivers).
- EDGKR indicates a specific packaging/lot variant (RoHS compliant, tape‑and‑reel option) used by TI.
Typical use:
- Interfaces a microcontroller to RS‑485 multi‑drop networks in industrial automation, building controls, motor drives, and PLCs.
In short, it’s a ready‑to‑use, reliable RS‑485 transceiver that simplifies implementing robust differential networks.

Here are the typical features of the SN65HVD3088EDGKR (high‑speed CAN transceiver):

- ESD and surge protection on I/O pins; robust protection against short to GND or VCC
- Operating temperature range: -40°C to +125°C
- RoHS-compliant, 8-pin package (EDGKR suffix, footprint variant)

16-pin TSSOP (Thin Shrink Small Outline Package), Pb-free/RoHS compliant.

- Pin count: 8 pins (SOIC-8/MSOP-8, package code EDGKR).
- Function: High-speed CAN transceiver. Interfaces a CAN controller to the CAN bus: TXD input to drive CANH/CANL, RXD output from the bus, CANH/CANL connected to the bus, with VCC/GND power and a standby/enable control (STB/EN).

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: TI is an American multinational semiconductor design and manufacturing company, one of the world’s largest producers of analog and embedded processing ICs, headquartered in Dallas, Texas.

- Automotive in-vehicle networks (ECUs, body/chassis, gateways)
- Industrial automation (PLC, motor drives, robotics, CAN subsystems)
- Instrumentation and data acquisition (sensors/actuators on CAN bus)
- CAN network gateways/bridges (CAN-to-CAN, CAN-to-Ethernet)
- Harsh-environment CAN nodes (rugged automotive/industrial ECU modules, diagnostics)
Note: SN65HVD3088EDGKR supports CAN 2.0A/B up to 1 Mbps with robust protection, suited for these applications.
