DS2156L

Telecom Overview

The DS2156L is a single-channel T1/E1/J1 transceiver designed for telecom interface applications. It operates within a supply voltage range of 3.135 V to 3.465 V, with a nominal working voltage of 3.3 V. The device supports data rates up to 2.048 Mb/s and functions in an ambient temperature range from 0°C to +70°C. Packaged in a 100-lead LQFP (14x14 mm) surface-mount format, it integrates line interface unit capabilities. The component exhibits humidity sensitivity and is classified under Telecom Interface ICs.

Telecom Feature Summary

Telecom Procurement Notes

Verify the specific suffix designation on the component marking against official datasheets to confirm exact electrical characteristics and package variant. Confirm RoHS compliance status as documentation may vary by production batch. Check for obsolescence notices or product discontinuance announcements prior to procurement planning.

Telecom Selection Notes

Select this component when a single-channel solution for T1, E1, or J1 protocols is required. Ensure the design environment supports the specified 3.3 V operating voltage and industrial temperature range. Verify that the 100-LQFP footprint aligns with the PCB layout constraints and assembly capabilities.

Telecom Part Context

This part belongs to the DS2156L series of telecom interface integrated circuits manufactured by Analog Devices Inc./Maxim Integrated. It serves as a specialized line interface unit for synchronous digital hierarchy applications, distinct from multi-channel variants or different protocol-specific transceivers within the manufacturer's portfolio.

Telecom Replacement Considerations

Consult official cross-reference tools for parametrically similar parts. Verify pin compatibility and electrical specifications before substituting with other T1/E1 transceivers.
