DS2154LA2

Drivers, Receivers, Transceivers Overview

The DS2154LA2+ is an enhanced E1 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for telecom interface applications. It operates as a single-channel Line Interface Unit (LIU) supporting full-duplex communication over the E1 protocol. The device functions within a supply voltage range of 4.75V to 5.25V and is housed in a 100-LQFP surface-mount package measuring 14x14 mm. It supports selectable 120Ω and 75Ω impedance interfaces. The component is currently classified as obsolete or discontinued.

Drivers, Receivers, Transceivers Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Availability is restricted, and sourcing may require checking legacy inventory or authorized distributors for remaining stock. Verification of authenticity and condition is critical due to the end-of-life status. Buyers should confirm specific lot dates and storage history before procurement.

Drivers, Receivers, Transceivers Selection Notes

Designers replacing this part must verify pin compatibility with alternative E1 transceivers from the same family or newer generations. Considerations include matching the 100-LQFP footprint and ensuring support for both 120Ω and 75Ω impedances. Electrical parameters such as supply voltage tolerance and operating temperature range must align with the original system requirements.

Drivers, Receivers, Transceivers Part Context

The DS2154LA2 belongs to the DS2154 series of enhanced E1 transceivers. It serves as a specialized interface chip for connecting digital equipment to E1 lines. The 'LA2' suffix typically denotes specific packaging or environmental ratings within the Maxim Integrated portfolio, distinct from standard variants like the DS2154L.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other parts within the DS2154 family, such as the DS2154L+ or DS2154LN, provided they meet the specific impedance and package requirements. Engineers should consult official datasheets to confirm functional equivalence and pinout compatibility before substitution.
