DS21E354N

Specialized ICS Overview

The DS21E354N is a single-channel E1 Line Interface Unit (LIU) manufactured by Analog Devices Inc. under the Maxim Integrated brand. It functions as a Single Chip Transceiver designed for telecom interface applications, supporting data rates of 2.048 Mb/s. The device operates within a supply voltage range of 3.135 V to 3.465 V and is rated for an operating temperature range from -40°C to +85°C. It utilizes surface-mount technology in an LQFP-100 package. This component integrates transmitter and receiver circuits for E1 line interfacing.

Specialized ICS Applications

• Telecom interface systems
• E1 line interfacing units

Specialized ICS Procurement Notes

Verify the specific manufacturer designation, as Analog Devices acquired Maxim Integrated. Confirm the package type is LQFP-100 and check for RoHS compliance status via official datasheets. Ensure the operating voltage requirements match the system design constraints before procurement.

Specialized ICS Selection Notes

Select this component for single-channel E1 applications requiring a compact solution. Verify compatibility with 3.3V logic levels if interfacing with digital controllers. Consider the LQFP-100 footprint during PCB layout. Compare against other series members like DS21354 or DS21554 if multi-channel or different protocol support is needed.

Specialized ICS Part Context

The DS21E354 belongs to the DS21x5y family of Single Chip Transceivers. These devices are designed to replace discrete solutions for T1/E1 line interfacing. The 'E' suffix typically denotes E1 operation, distinguishing it from T1 variants. It serves as a key component in telecommunications infrastructure for signal conditioning and line driving.

Specialized ICS Replacement Considerations

Check for direct pin-compatible substitutes within the DS21354 or DS21554 families. Verify functional equivalence regarding E1 signaling standards. Consult official cross-reference tools for confirmed alternatives.
