LTV-847

Transistor, Photovoltaic Output Optoisolators Overview

The LTV-847 is a four-channel transistor output optocoupler manufactured by Lite-On. It features a 16-pin PDIP package with DC input and NPN phototransistor outputs. Key electrical parameters include an isolation voltage of 5000 Vrms, a maximum collector-emitter voltage of 35 V, and a maximum collector current of 50 mA. The device operates within a temperature range of -30°C to 110°C. Typical performance metrics specify a minimum Current Transfer Ratio (CTR) of 50% at IF=5mA, with rise and fall times of approximately 4µs and 3µs respectively. The forward voltage is typically 1.2V to 1.4V.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix or variant code against the manufacturer's official datasheet to ensure compatibility with required isolation ratings and pin configurations. Confirm RoHS compliance status and packaging type directly with authorized distributors to avoid counterfeit components. Cross-reference the part number with the latest revision history to ensure all technical specifications remain current before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated signal paths are needed in a compact form factor. Ensure the application voltage does not exceed the 35 V collector-emitter limit. Verify that the required CTR meets the system's logic level thresholds at the operating temperature range. Consider the DIP-16 footprint constraints during PCB layout design to accommodate the through-hole mounting style.

Transistor, Photovoltaic Output Optoisolators Part Context

The LTV-847 belongs to the LTV series of photocouplers from Lite-On Technology Corporation. It is designed as a high-density mounting type device, offering a solution for applications requiring multiple isolated channels without increasing board area.
