Detailed Description

LTC2801CDE is a Linear Technology/Analog Devices transceiver IC in a compact DFN package. It is part of the LTC28xx communications interface family and is commonly used as a high‑speed CAN physical layer transceiver for robust, differential bus communications in noisy environments.

Main Category: Integrated Circuits (ICs)

Small Classification: Specialized ICs

Description from stock info: LINEAR DFN

Date code on this lot: 19+

Available stock quantity: 3320 units

Key Features

Robust differential bus interface designed for high‑speed networked control systems (typical use: CAN physical layer)

Single-supply operation with logic‑level I/O compatible with common microcontrollers

Low-power standby/sleep modes to reduce system current

Thermal shutdown and dominant-timeout style bus protection (typical for this family)

High ESD protection on bus pins and wide common-mode operating range for noisy environments

Glitch-free mode transitions and failsafe receiver behavior when bus is idle or open

Pin functions typically include: TXD, RXD, CANH, CANL, VCC, GND, and an Enable/Standby control (refer to datasheet for exact pinout)

DFN package with exposed thermal pad for improved heat dissipation and compact PCB footprint

Key Advantages

Reliable communication in harsh industrial and automotive environments thanks to differential signaling and strong bus protection

Low standby current helps extend system energy efficiency in always‑on or battery‑powered designs

Compact DFN saves board space without sacrificing thermal performance

Proven Linear Technology/Analog Devices quality, backed by Y‑IC’s sourcing and support

Flexible control pins enable simple integration with a wide range of MCUs and system power modes

Packaging

Package type: DFN with exposed thermal pad (Linear package code “DE”)

Distributor case reference: 1748 (internal case/mold code reference used by some catalogs)

Body material: Molded thermo-set epoxy, leadframe with leadless contacts

Nominal size: Compact 3 mm x 3 mm class DFN footprint (refer to datasheet package drawing for exact dimensions and land pattern)

Pin configuration: Leadless perimeter pads plus center exposed pad for heat sinking; typical pins include CANH, CANL, TXD, RXD, VCC, GND, EN/STBY (see datasheet for the definitive pin map)

Thermal characteristics: Exposed pad lowers junction-to-ambient thermal resistance; actual θJA depends on PCB copper area and airflow (see datasheet thermal data)

Electrical properties overview: Single-supply operation, logic-level digital I/O, robust differential bus drivers/receivers with protection features (see datasheet for voltage ranges, timing, and current limits)

Moisture sensitivity: DFN packages are typically shipped dry-packed and are reflow-compatible per JEDEC J‑STD‑020; check reel/bag label for exact MSL rating

Shipment form: Tape-and-reel for automated assembly is standard; other packing on request

Lifecycle

Status: As of our latest update, LTC2801CDE is an active, orderable device within the LTC28xx family.

Not nearing discontinuation to our knowledge. For real-time lifecycle visibility and inventory, check our website or contact Y‑IC sales.

Equivalent or alternative models:

- Same-family/close ADI options: Consider LTC2802 (family variant), newer ADI/Linear CAN transceivers such as LTC2875/LTC2876 (fault‑tolerant options), or isolated CAN solutions like ADM3050/ADM3051 if galvanic isolation is required.

- Cross‑vendor functional alternatives (depending on required voltage, speed, and protection): TI SN65HVD230/231/232 (3.3 V CAN), NXP TJA1042/TJA1051, Microchip MCP2561/MCP2562, Infineon TLE9250/TLE9251.

Selection notes: The best cross depends on supply voltage, bus speed, ESD/fault tolerance needs, standby behavior, and pinout. If you need a 1:1 alternative or automotive grade, contact Y‑IC for a tailored cross‑reference list.

Key Application Areas

Automotive and transportation CAN networks (powertrain, body control, diagnostics)

Industrial automation and factory networking (PLC, motion control, robotics)

Building automation (HVAC, access control, elevators)

Medical and fitness equipment with robust networked control

Marine, agriculture, and off‑highway vehicles

Any distributed control system requiring reliable, high‑speed differential communications
