CY74FCT827CTSOCT

Overview

The CY74FCT827CTSOCT is a Tri-State 10-Bit buffer and line driver from the FCT logic series by Texas Instruments. It utilizes CMOS technology and features non-inverting polarity with ten input and ten output lines. The device operates within a supply voltage range of 4.75 V to 5.25 V, drawing a maximum operating power current of 4.1 mA and maintaining a static current of 100 uA. It provides high-level output currents of -32 mA and low-level output currents of 64 mA. The component exhibits a propagation delay of 14 ns and functions reliably across an operating temperature range of -40°C to +85°C. It is housed in a 24-pin SOIC package.

Feature Summary

• Provides ten-channel buffering and driving capabilities with tri-state outputs for bus isolation.

Applications

• Signal buffering in digital systems
• Line driving applications requiring high current capability

Procurement Notes

Verify the specific suffix 'CTSOCT' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure compatibility with standard surface-mount assembly processes for SOIC-24 packages. Cross-reference the manufacturer part number directly with the datasheet to validate all electrical parameters before integration into designs.

Selection Notes

Select this component when ten independent buffered channels are required with tri-state control. The FCT series offers TTL-compatible inputs suitable for interfacing with various logic families. Consider the 14 ns propagation delay and 64 mA low-level sink current for driving moderate loads. Verify that the 24-pin SOIC footprint fits the target PCB layout constraints.

Part Context

This part belongs to the CY74FCT827T family of 10-bit buffers. It shares functional similarities with other FCT series drivers but is distinct due to its ten-channel architecture. The SOIC-24 package distinguishes it from narrower variants like the 8-bit CY74FCT541 or CY74FCT240. It serves as a dedicated solution for expanding bus width in digital circuits.

Replacement Considerations

Check for direct equivalents within the CY74FCT827T family. Verify pinout compatibility if substituting with other 10-bit buffers. Confirm that alternative parts meet the same 4.75V–5.25V supply requirements and SOIC-24 package dimensions.
