RoHS non-compliant — verify your assembly house can handle the tin-lead finish if your process is RoHS-exempt (military, aerospace, some industrial). ## Sourcing posture and RFQ No official second-source or pin-compatible alternative listed — the DS2155GNB is the sole member of this specific order code.","metaTitle":"DS2155GNB Single-Chip Transceiver E1/J1/T1 HDLC - Analog","metaDescription":"DS2155GNB from Analog Devices: single-chip transceiver for E1, J1, T1 with HDLC.
