CD74HC4049NSR

Overview

The CD74HC4049NSR is a high-speed CMOS logic integrated circuit manufactured by Texas Instruments. It functions as a hex buffer containing six independent input-output channels. The device supports both inverting and non-inverting configurations, allowing flexible signal routing within digital circuits. It operates on a supply voltage range of 2 V to 6 V and utilizes a 16-pin SOIC surface-mount package. The component is designed for robust performance across an extended industrial temperature range.

Feature Summary

• Provides six independent buffering channels with configurable inversion states
• Supports bidirectional data flow through versatile input-output architecture
• Features high noise immunity suitable for complex digital environments

Applications

• Level shifting between different voltage domains
• Signal isolation in digital communication buses
• Address bus buffering in microprocessor systems

Procurement Notes

Verify the specific suffix NSR indicates the tape-and-reel packaging format upon ordering. Confirm that the intended application requires the dual-function capability of this hex buffer rather than a single-purpose driver. Ensure compatibility with the target PCB footprint for the 16-SOIC package before finalizing procurement specifications.

Selection Notes

Select this component when design requirements demand multiple buffered channels within a single package footprint. Consider its wide operating voltage range if the system interfaces with varying logic levels. Evaluate the trade-off between the flexibility of invertible buffers versus dedicated unidirectional drivers for space-constrained layouts.
