IDT74FST32383FPG

Overview

The IDT74FST32383FPG is a high-speed CMOS octal bus transceiver featuring three-state outputs, designed for memory and microprocessor systems. It operates with a supply voltage range of 2.7V to 3.6V. The device supports bidirectional data transfer between two buses, providing low on-resistance and controlled switching speeds. It includes latch-up proof design and ESD protection exceeding 2000V per the Human Body Model. The FPG package is a 44-pin Thin Small Outline Package (TSOP) with a 0.5mm pitch.

Feature Summary

• Octal bus transceiver architecture enabling bidirectional data flow
• Three-state outputs for efficient bus line management
• Robust ESD protection compatible with high-reliability environments
• CMOS technology ensuring low power consumption

Applications

• Memory modules requiring high-speed data transfer
• Microprocessor-based system interconnects
• Bus-oriented architectures in computing equipment

Procurement Notes

Verify the specific suffix 'FPG' confirms the 44-pin TSOP package and lead-free status. Confirm RoHS compliance through official manufacturer documentation or certified datasheets. Ensure the component matches the original specification for voltage range and pinout compatibility before integration into existing designs.

Selection Notes

Select this component when an octal transceiver with 3.3V operation is required. Consider the TSOP-44 footprint constraints during PCB layout. Verify that the input logic levels match the source driver specifications. Evaluate thermal requirements based on the specific application load and ambient conditions.

Part Context

This part belongs to the FST (Fast Switching Technology) family from Integrated Device Technology. These devices are engineered for high-performance digital applications requiring fast propagation delays and low power dissipation. The series complements other logic families by offering improved speed-to-power ratios suitable for modern embedded systems.

Replacement Considerations

Check for direct pin-compatible alternatives within the same FST family. Verify equivalent electrical characteristics such as propagation delay and output drive strength. Ensure the replacement maintains the same package type and operating voltage range to avoid redesign efforts.
