Overview
The ACPL-268KL-100 is a high-speed, dual-channel optocoupler manufactured by Broadcom Limited. It features a hermetically sealed ceramic DIP-16 package designed for military and aerospace reliability standards. The device supports a data rate of 10 Mb/s with a common mode transient immunity of 1 kV/µs. Key electrical parameters include a forward current of 20 mA, forward voltage of 1.5 V, and power dissipation of 200 mW. Rise and fall times are specified at 90 ns and 40 ns respectively. It operates within a temperature range of -55°C to +125°C and provides 1500 Vdc isolation.
Feature Summary
- Hermetically sealed ceramic construction ensuring high reliability in harsh environments
- Dual-channel architecture with Schottky-clamped open collector outputs
- High common mode transient immunity for noise-sensitive applications
Applications
- Military and aerospace systems requiring MIL-PRF-38534 compliance
- Industrial line receivers and voltage translation circuits
- Medical transport equipment demanding high isolation integrity
Procurement Notes
Verify the specific suffix (e.g., -100 vs -200) against the required DLA drawing number or quality level. Confirm that the procurement source is an authorized distributor or the manufacturer directly. Ensure the component meets the specific Class H or K testing requirements if mandated by the system design. Check for RoHS status as indicated in official documentation, noting potential variations for military-grade parts.
Selection Notes
Select this component when high-speed digital isolation is required alongside strict environmental durability. The dual-channel configuration reduces board space compared to single-channel alternatives. Verify compatibility with TTL logic levels due to the open collector output structure. Consider the thermal management capabilities given the 200 mW power dissipation limit in enclosed military enclosures.
Part Context
This part belongs to the ACPL-2 series of high-speed optocouplers from Broadcom. It is produced under MIL-PRF-38534 certification on qualified manufacturing lines. The device is listed on the Defense Logistics Agency (DLA) Qualified Manufacturers List (QML-38534). It utilizes GaAsP LEDs coupled to high-speed photodetectors within a shielded ceramic package.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 16-pin CDIP package, 10 Mb/s speed, and MIL-PRF-38534 qualification level.
