HCPL-7611-500E

The HCPL-7611-500E optocoupler is a versatile solution with key features such as low input current (2 mA to 10 mA range), CMOS/TTL compatibility, guaranteed switching threshold, and high Common Mode Rejection (CMR) with impressive values (15,000 V/μs typical at VCM = 1000 V, IF = 4 mA). Offering high-speed capabilities (10 Mbd typical) and guaranteed AC/DC performance across a wide temperature range (-40°C to 85°C), it meets diverse application requirements. The device holds safety certifications (IEC/EN/DIN EN 60747-5-2, UL, CSA) and a lead-free option ("-000E"). With low supply current, low Propagation Delay Skew (TPSK), and reliability in signal isolation, the HCPL-7611-500E is a robust choice for applications demanding precise logic gate functionality and signal integrity.

The HCPL-7601/11 is a low input current version of the HCPL-2601/11 and 6N137 (without enable). The optically coupled gates combine an AlGaAs highefficiency light emitting diode and an integrated high gain photon detector to create a low input current device for low power applications. The output of the detector IC is an open collector Schottky-clamped transistor. The internal shield provides a guaranteed common mode transient immunity specification of 10,000 V/µs (HCPL-7611). This unique design provides maximum ac and dc circuit isolation while achieving CMOS and TTL compatibility. The optocoupler ac and dc operational parameters are guaranteed from -40°C to 85°C with no derating required allowing trouble free system performance. This product is suitable for high speed logic interfacing, input/output buffering, and applications that require low input-current switching levels.

The small device geometries inherent to the design of this bipolar component increase the component's susceptibility to damage from electrostatic discharge (ESD). It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD.
