LTC2801IDE Equivalent & Substitute Parts

Part Overview

The LTC2801IDE is a half-duplex RS232 transceiver interface IC manufactured by Analog Devices Inc., housed in a 12-DFN (4x3) surface mount package. This device integrates a single driver and receiver pair for RS232 serial communication applications, supporting data rates up to 250 kbps across a wide supply voltage range of 1.8V to 5.5V.

The LTC2801IDE carries an obsolete product status, indicating that Analog Devices Inc. has discontinued active production and support for this specific part number variant. Identifying equivalent and substitute parts is necessary to ensure continued availability for new designs, maintenance applications, and production continuity where RS232 transceiver functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LTC2801IDE is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• RS232 protocol compliance with half-duplex operation
• Single driver and single receiver configuration (1/1)
• Data rate capability of 250 kbps minimum
• Supply voltage range of 1.8V to 5.5V
• Receiver hysteresis of 400 mV
• Operating temperature range of -40°C to 85°C

Physical and Manufacturing Specifications:

• 12-pin DFN package with exposed pad (12-WFDFN)
• Surface mount technology
• Moisture sensitivity level MSL 1

The substitute part LTC2801IDE#PBF maintains identical electrical and mechanical specifications to the main part number, with the primary distinction being packaging format (tube packaging) and active product status from the manufacturer.

Parameter Comparison

Engineering Selection Recommendations

The LTC2801IDE#PBF serves as the direct substitute for the obsolete LTC2801IDE. Both parts share identical electrical performance specifications and physical package dimensions, ensuring functional and mechanical compatibility in circuit applications.

The LTC2801IDE#PBF maintains active product status with Analog Devices Inc., providing access to current manufacturing, quality assurance, and technical support. This part carries RoHS3 compliance and REACH unaffected status, meeting contemporary regulatory requirements for electronic component procurement.

Selection of LTC2801IDE#PBF is appropriate for applications requiring RS232 half-duplex transceiver functionality within the specified electrical and thermal operating ranges. The packaging format difference (tube versus standard packaging) does not affect electrical or mechanical performance and relates only to distribution and handling methods.

Frequently Asked Questions (FAQ)

Q: Can LTC2801IDE#PBF be used as a direct replacement for LTC2801IDE?

A: Yes. The LTC2801IDE#PBF is electrically and mechanically equivalent to the LTC2801IDE. Both parts feature identical RS232 transceiver specifications, 1/1 driver/receiver configuration, 250 kbps data rate capability, 1.8V to 5.5V supply voltage range, and 12-DFN (4x3) surface mount package. The primary difference is product status and packaging format.

Q: What is the significance of the product status difference between these parts?

A: The LTC2801IDE carries obsolete status, indicating discontinued manufacturing and support from Analog Devices Inc. The LTC2801IDE#PBF maintains active status, ensuring ongoing availability, current manufacturing processes, and manufacturer technical support. For new designs and long-term production requirements, the active part number is preferred.

Q: Are there any compliance or certification differences between these parts?

A: The LTC2801IDE#PBF includes RoHS3 compliance and REACH unaffected status documentation. Both parts maintain MSL 1 moisture sensitivity level. The LTC2801IDE#PBF carries EAR99 ECCN classification, while the obsolete variant is marked OBSOLETE for export control purposes.

Q: Does the packaging format affect circuit performance?

A: No. The packaging format difference (tube packaging for LTC2801IDE#PBF versus standard packaging for LTC2801IDE) relates only to distribution, storage, and handling methods. Electrical performance, thermal characteristics, and mechanical fit within the 12-DFN package remain identical.

Q: What are the critical parameters for confirming substitution compatibility?

A: Substitution compatibility is confirmed by matching the following parameters: RS232 protocol, half-duplex operation, 1/1 driver/receiver configuration, 250 kbps data rate, 1.8V to 5.5V supply voltage range, 400 mV receiver hysteresis, -40°C to 85°C operating temperature range, and 12-WFDFN exposed pad package type.
