Voltage - Isolation: 5000Vrms
Current Transfer Ratio range: 20% to 300% @ 1mA
Rise / Fall Time: 4µs, 3µs
Input Type: AC, DC
Output Type: Transistor
Current - Output / Channel: 50mA
Vce Saturation (Max): 200mV
Operating Temperature: -30°C ~ 100°C
Mounting Type: Surface Mount
Package / Case: 16-SMD, Gull Wing

Engineering Selection Recommendations

All three parts—ACPL-844-360E, ACPL-844-300E, and LTV-844S—are active production components with ROHS3 compliance and MSL Level 1 rating. Selection between these parts should be based on the following factors:

ACPL-844-360E (Primary Part): Broadcom Limited manufacture with 5600 units in stock. Maximum output voltage rating of 70V.

ACPL-844-300E (Parametric Equivalent): Broadcom Limited manufacture with identical electrical specifications to the primary part. Suitable for direct substitution where Broadcom sourcing is preferred. 1981 units in stock.

LTV-844S (Manufacturer-Recommended Equivalent): Lite-On Inc. manufacture with maximum output voltage rating of 35V. This part differs from the primary part in maximum output voltage specification. Selection of LTV-844S is appropriate only when circuit design requirements do not exceed 35V output voltage. 16475 units in stock, providing superior availability.

All parts maintain identical isolation voltage, channel count, current transfer ratio range, rise/fall time characteristics, input/output types, saturation voltage, operating temperature range, and package configuration.

Frequently Asked Questions (FAQ)

Q: Can ACPL-844-300E be used as a direct replacement for ACPL-844-360E?

A: Yes. ACPL-844-300E is a parametric equivalent with identical electrical and mechanical specifications. Both are manufactured by Broadcom Limited and share the same 16-SMD, Gull Wing package configuration.

Q: What is the key difference between ACPL-844-360E and LTV-844S?

A: The maximum output voltage rating differs: ACPL-844-360E is rated to 70V, while LTV-844S is rated to 35V. All other electrical parameters, including isolation voltage, current transfer ratio, rise/fall time, and output current per channel, are identical. LTV-844S substitution is valid only when circuit design does not require output voltages exceeding 35V.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 16-SMD, Gull Wing package configuration with identical pinout and mechanical dimensions, enabling direct PCB-level substitution.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. ACPL-844-360E, ACPL-844-300E, and LTV-844S are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating. All are REACH unaffected and classified under ECCN EAR99.

Q: Which part offers the best supply availability?

A: LTV-844S currently has the highest inventory at 16475 units. ACPL-844-360E has 5600 units, and ACPL-844-300E has 1981 units in stock.

Q: Can LTV-844S be used in all applications designed for ACPL-844-360E?

A: LTV-844S can be used in applications where the maximum output voltage requirement does not exceed 35V. For applications requiring output voltages above 35V, ACPL-844-360E or ACPL-844-300E must be used.
