74FST3861DW

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74FST3861DW is a 10-bit high-performance bus driver housed in a 24-pin SOIC package. It functions as a bus switch with a 1x1 configuration, designed for TTL logic applications. The device features three-state outputs and supports bidirectional data transfer. Key electrical parameters include a maximum propagation delay of 9 ns at specified load conditions. It operates within a supply voltage range of 4.5V to 5.5V and withstands output currents of up to 8mA in both low and high states. The component is rated for an operating temperature range from -40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed bus interface circuits requiring 10-bit width
• TTL to CMOS level translation systems
• Data buffer applications in industrial control modules

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' confirms the SOIC-24 package and tape-and-reel or rail quantity details against the manufacturer's latest datasheet. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies by region. Ensure the ordering part number matches the exact pinout and electrical specifications required for your design integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 10-bit wide bus driver is required with TTL-compatible input thresholds. The VHC/VHCT logic family offers faster switching speeds compared to standard HC/HCT series. Consider the 24-pin SOIC footprint for PCB layout constraints. Verify that the 5.5V maximum supply voltage aligns with the system power rails and that the 9ns delay meets the timing requirements of the target application.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74FST (Fast Switching Technology) logic family from onsemi, optimized for high-speed performance. It serves as a bridge between different logic families, specifically handling TTL inputs with CMOS outputs. The 74FST series is distinct from standard 74HC or 74LV series due to its superior speed characteristics and specific drive capabilities for demanding bus architectures.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-to-pin replacements within the same 74FST family, such as other 10-bit bus drivers like the 74FST3862 if inverted outputs are needed. Verify compatibility with alternative manufacturers offering equivalent FST logic devices. Ensure any substitute maintains the same 24-pin SOIC package dimensions and electrical ratings.
