Broadcom ACPL-K70A/K73A High-Speed Optocouplers

Broadcom ACPL-K70A/K73A High-Speed Optocouplers are high gain series couplers that use LED and an integrated high gain photodetector. This provides an extremely high current transfer ratio between input and output. These optocouplers come with separate pins for the photodiode and output stage that result in LVTTL-compatible saturation voltages and high-speed operation. The V_CC and V_O terminals tied together to achieve conventional photodarlington operation. These ACPL-K70A/K73A optocouplers feature low input current, high current gain, low power consumption, and base access allows gain bandwidth adjustment.

The ACPL-K70A/K73A optocouplers are surface-mount devices that are packaged in an industry-standard stretched SOIC-8 footprint. This stretched SOIC-8 does not require through holes in a PCB. The ACPL-K70A/K73A high-speed optocouplers are ideal for use in LVTTL/LVCMOS or other low-power applications.
