74HC244FPDVEL-E

Overview

The 74HC244FPDVEL-E is an octal buffer and line driver manufactured by Renesas Electronics Corporation. It features two independent elements, each handling four bits of data with non-inverted logic. The device provides three-state outputs, allowing for effective bus driving and isolation in digital systems. It operates within a voltage range supporting up to 6V applications and functions reliably across a wide temperature spectrum from -55°C to 125°C.

Feature Summary

• Provides octal buffering with non-inverted signal transmission
• Features dual four-bit elements for flexible data routing
• Supports three-state output control for bus isolation

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffered oscillators
• Open-drain line drivers for high-voltage or current loading

Procurement Notes

Verify the specific suffix 'VEL' against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure the operating temperature range meets system requirements. Confirm RoHS compliance status directly with the manufacturer's latest datasheet before procurement.

Selection Notes

Select this component when octal buffering with three-state capability is required. Consider the HC series speed and power characteristics relative to system needs. Verify that the input voltage levels are compatible with the driving source logic family.

Part Context

This part belongs to the HD74HC Series, a standard family of 5V drive bipolar general-purpose logic ICs. The series has a long market history and high penetration. The 74HC244 specifically addresses the need for high-drive capacity buffers in complex digital architectures.

Replacement Considerations

Check for direct pin-compatible substitutes within the same 74HC family. Verify electrical parameters such as propagation delay and output current capabilities match the original design requirements.
