TLP2955(D4,F)

Logic Output Optoisolators Overview

The TLP2955(D4,F) is a logic output photocoupler manufactured by Toshiba Semiconductor and Storage. It integrates a GaAlAs light-emitting diode with a high-gain, high-speed photo detector to provide electrical isolation. The device features a push-pull or totem pole output configuration, supporting a data rate of 5Mbps. It offers an isolation voltage of 5000Vrms and a common-mode transient immunity (CMTI) of 20kV/µs. The component operates within a supply voltage range of 3V to 20V and delivers an output current of 25mA per channel. Maximum propagation delays for both low-to-high and high-to-low transitions are specified at 250ns.

Logic Output Optoisolators Feature Summary

Logic Output Optoisolators Procurement Notes

Verify the specific suffix D4,F against the manufacturer's official datasheet to confirm package type and compliance status. Ensure the ordering code matches the required lead-free and RoHS compliant specifications. Cross-reference the supplier's documentation with Toshiba Semiconductor and Storage's official product listings to validate authenticity and technical parameters before purchase.

Logic Output Optoisolators Selection Notes

Select this component when a single-channel isolated logic interface with high-speed performance is required. The 5Mbps data rate and low propagation delay make it suitable for applications demanding fast response times. The push-pull output eliminates the need for external pull-up resistors in many logic circuits. Verify that the operating supply voltage range of 3V to 20V aligns with the system design requirements.
