Description

The SN65LBC174A16DWR is a Texas Instruments dual-channel RS-422/RS-485 transceiver. It provides two independent driver/receiver pairs to convert between single-ended microcontroller logic levels and differential A/B bus signals used in RS-422/RS-485 networks. Each channel has its own DI/RO with DE/RE control, enabling full- or half-duplex operation, and the device includes fail-safe receivers and high-impedance when disabled. It operates from a single supply in the 3.0–5.5 V range and supports high-speed differential signaling suitable for industrial networks, with protections for bus faults and robust ESD. The “A16” in the part number denotes the package variant, which is TI’s 16-pin TSSOP (DWR) package. Typical applications include industrial automation, PLCs, building automation, and any embedded system needing two RS-485/RS-422 interfaces. For exact electrical specs (data rate, input thresholds, and protection features), consult the TI datasheet.

Pinout

- Pin count: 16 pins (DWR package).
- Function: Octal (8-bit) bidirectional bus transceiver with 3‑state outputs; transfers data between two 8-bit buses with direction control (DIR) and output enable (OE).

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog and mixed-signal integrated circuits (e.g., RS-422/RS-485 transceivers) and other electronics components; one of the world’s largest semiconductor producers.

Application

SN65LBC174A16DWR is a quad RS-485/RS-422 transceiver (differential, long-distance, noise-immune). Typical application areas:
- Industrial automation and process control (multi-drop RS-485 networks)
- Building automation (HVAC, lighting, security)
- Remote data acquisition and instrumentation in noisy environments
- PLCs, remote I/O, and distributed control panels
- Telemetry and medical/testing equipment requiring robust long-distance signaling
Also suitable for any application needing reliable differential communication over long cables with good noise rejection.

Package

A 16-pin Small Outline Integrated Circuit package (SOIC-16).
