CD74FCT16827ATSM

Overview

The CD74FCT16827ATSM is a high-speed FAST CMOS buffer manufactured by Harris Corporation. It features two independent non-inverting elements, each providing ten bits of buffering capability for a total of twenty output lines. The device utilizes a 56-pin SSOP surface-mount package and operates within a temperature range of -40°C to 85°C. Designed for low voltage applications up to 5.5V, it offers three-state outputs with series resistors to manage signal integrity in high-speed digital systems.

Feature Summary

• Provides dual-channel buffering with ten bits per channel for expanded data path management
• Features three-state outputs equipped with internal series resistors for controlled signal transitions
• Utilizes FAST CMOS technology to achieve high switching speeds with low power consumption

Applications

• High-speed parallel data bus buffering in computer systems
• Clock distribution networks requiring multiple buffered outputs
• Interface circuits between microprocessors and peripheral devices

Procurement Notes

Verify the specific suffix 'ATSM' to confirm the 56-pin SSOP package and industrial temperature rating. Ensure compatibility with existing PCB footprints for SSOP-56 components. Confirm that the non-inverting logic function aligns with the system design requirements before procurement.

Selection Notes

Select this component when a high-density buffer solution is required for twenty-bit wide buses. The dual-element architecture simplifies layout compared to using multiple single-channel buffers. Consider the series resistor feature for impedance matching in high-frequency applications where signal reflection control is critical.

Part Context

This part belongs to the FCT (FAST CMOS Technology) family from Harris Corporation, designed for high-performance digital logic applications. The FCT series is known for combining the speed of ECL with the low power of CMOS, making it suitable for battery-operated and high-speed computing environments.

Replacement Considerations

Check for direct pin-compatible alternatives within the same FCT family or cross-reference with other manufacturers offering similar 20-bit non-inverting buffers in SSOP-56 packages. Verify electrical characteristics such as propagation delay and output drive strength to ensure functional equivalence.
