This document introduces the technical data and features of an IrDA® compliant 4 Mb/s 5 V infrared transceiver, including full compliance with IrDA 1.1 physical layer specifications, typical link distance greater than 1.5 m, compatibility with ASK, HP-SIR, and TV remote, etc.
The HSDL-3601 is a low‑profile infrared transceiver module that complies with IrDA 1.1 and IEC825‑Class 1 eye‑safe specifications. It features a high‑speed 870 nm LED, a silicon PIN diode, and an integrated driver/receiver IC, offering data rates from 9.6 kb/s up to 4 Mb/s while consuming very low power in shutdown mode.
The document lists detailed electrical and optical specifications, pin‑out tables, recommended external components, absolute maximum ratings, and ordering information for the two package options (front‑view #007/#017 and top‑view #008/#018). Application notes cover use in digital imaging, data communication, telecommunications, and small industrial/medical instrumentation.
