Overview
The IDT74FCT540TPY is an octal buffer and line driver manufactured by Integrated Device Technology using advanced dual metal CMOS technology. It features non-inverting logic with three-state outputs, designed for high-performance digital applications. The device operates within a supply voltage range of 4.75V to 5.25V and supports an operating temperature range from -40°C to +85°C. It provides true TTL input and output compatibility while maintaining low power consumption typical of CMOS devices.
Feature Summary
- Non-inverting octal buffer configuration with three-state outputs
- True TTL input and output compatibility
- Low input and output leakage current characteristics
- CMOS power level operation
Applications
- High-performance digital buffering systems
- Line driving applications requiring TTL compatibility
- Three-state bus driver implementations
Procurement Notes
Verify the specific suffix 'TPY' corresponds to the 20-SSOP package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status as historical data indicates potential lead-containing variants. Ensure the supplier provides official documentation matching the IDT part number to avoid confusion with similar FCT series components.
Selection Notes
Select this component when non-inverting signal buffering with three-state control is required in a 20-pin surface-mount package. It is suitable for designs needing TTL compatibility alongside CMOS power efficiency. Consider the 4.75V to 5.25V supply constraint and ensure the application environment falls within the specified industrial temperature range.
Part Context
This part belongs to the IDT 74FCT series of fast CMOS logic devices. The 74FCT540 specifically denotes an octal buffer/line driver. The 'TPY' suffix typically identifies the plastic SSOP package variant. This series is engineered for high-speed digital interfaces where low power and strong drive capability are essential.
Replacement Considerations
Check for direct substitutes within the same FCT family that share the 20-SSOP footprint and electrical specifications. Verify pinout compatibility and voltage levels before substituting with other manufacturers' octal buffers.
