TLP2408(F)

Logic Output Optoisolators Overview

The TLP2408(F) is a high-speed logic output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates a GaAlAs infrared LED with a high-gain, high-speed photo detector housed in an 8-pin SO package. The device features a totem-pole output stage capable of both current sourcing and sinking, providing push-pull drive capabilities. It includes an internal Faraday shield ensuring a common-mode transient immunity of ±15 kV/µs. Key electrical parameters include a maximum forward current of 10 mA, an insulation voltage of 3750 Vrms, and a data transmission rate up to 5 Mbps. The operating temperature range spans from -40°C to 100°C.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix designation against official Toshiba documentation to confirm pinout compatibility and packaging variations. Ensure that the selected component meets the required insulation voltage ratings for the intended application environment. Cross-reference the manufacturer's latest datasheet to confirm active status and availability, as product lifecycles may change. Confirm RoHS compliance requirements align with project specifications before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when high-speed signal isolation is required between low-voltage logic circuits and higher voltage domains. The push-pull output architecture makes it suitable for driving loads directly without additional buffering stages. Consider the ±15 kV/µs common-mode transient immunity for environments with rapid voltage fluctuations. Evaluate the thermal performance within the specified -40°C to 100°C operating range to ensure reliability under varying environmental conditions.

Logic Output Optoisolators Part Context

The TLP2408 belongs to Toshiba's family of high-speed photocouplers designed for robust signal isolation. It complements other models like the TLP2405, which offers a non-inverting buffer output. This series addresses the need for fast response times and high noise immunity in modern electronic systems. The integration of the Faraday shield distinguishes it from standard optocouplers lacking such protection mechanisms.
