• Number of Channels: 4
• Voltage - Isolation: 2500Vrms
• Common Mode Transient Immunity: 10kV/µs minimum
• Output Type: Open Collector, Schottky Clamped
• Current - Output / Channel: 50 mA
• Data Rate: 15MBd
• Voltage - Supply: 3V ~ 5.5V
• Operating Temperature Range: -40°C ~ 100°C
• Package / Case: 16-SOIC

The ACSL-6400-56TE meets all electrical and mechanical substitution criteria, maintaining identical functional specifications while differing in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The ACSL-6400-56TE is the direct functional equivalent of the ACSL-6400-56T. Both parts share identical electrical characteristics, timing specifications, and mechanical packaging. The primary distinction is product lifecycle status: the ACSL-6400-56T is Obsolete, while the ACSL-6400-56TE is Active.

For new designs and ongoing production, the ACSL-6400-56TE is the appropriate selection. This part maintains full electrical and mechanical compatibility while offering the advantage of Active product status and ROHS3 compliance, addressing regulatory requirements for modern manufacturing environments.

For legacy system maintenance where the original ACSL-6400-56T is specified, the ACSL-6400-56TE provides drop-in compatibility without circuit redesign or re-qualification.
