CD74FCT2827ATQM

Overview

The CD74FCT2827ATQM is a non-inverting buffer manufactured by Harris Corporation, belonging to the FCT logic series. It features a single element with ten bits per element and provides three-state outputs. The device operates within a supply voltage range of 1.65V to 5.5V and supports an operating temperature range of -40°C to 85°C (TA). It utilizes Schmitt trigger inputs and push-pull outputs for signal integrity. The component is housed in a 24-QSOP surface-mount package.

Feature Summary

• Features Schmitt trigger inputs for noise immunity
• Provides three-state output capability for bus driving
• Utilizes push-pull output structure

Applications

• Bus-oriented systems requiring signal buffering
• Clock distribution networks
• Memory address/data bus drivers

Procurement Notes

Verify the manufacturer origin, as Harris Corporation assets were acquired. Confirm the specific suffix 'ATQM' corresponds to the 24-QSOP package and tape/reel or bulk packaging requirements. Ensure RoHS compliance status matches project specifications, as older Harris parts may not meet current standards. Validate the operating temperature grade against environmental constraints.

Selection Notes

Select this component when a high-speed, low-voltage compatible buffer with ten-bit width is required. The FCT series offers compatibility with standard TTL levels while supporting lower CMOS voltages. The QSOP package is suitable for space-constrained surface-mount designs. Verify input threshold requirements align with the Schmitt trigger specification for noisy environments.

Part Context

This part belongs to the Harris FCT (Fast CMOS) family, designed for high-speed digital applications. The FCT series bridges the performance gap between standard CMOS and TTL logic. Harris Corporation was a prominent semiconductor manufacturer before its logic division was acquired by other entities, affecting current sourcing channels.

Replacement Considerations

Check for direct pin-compatible equivalents from current manufacturers holding Harris logic IP rights. Verify electrical parameters such as propagation delay and drive strength against modern replacements. Ensure the replacement maintains the 24-QSOP footprint if board space is critical.
