CD74HC4049PWT

Overview

The CD74HC4049PWT is a high-speed CMOS logic device manufactured by Texas Instruments, featuring six inverting buffers within a single integrated circuit. It operates on a supply voltage range of 2 V to 6 V and supports an operating temperature range from -55 °C to +125 °C. The component utilizes a 16-pin TSSOP surface-mount package and delivers push-pull outputs with a maximum output current capability of 5.2 mA for both high and low states. It is supplied in tape-and-reel packaging suitable for automated assembly processes.

Feature Summary

• Provides six independent inverting buffer channels for signal inversion and level shifting applications.
• Features high-speed CMOS technology designed for efficient operation across wide voltage ranges.
• Utilizes a push-pull output structure to drive loads effectively without requiring external pull-up or pull-down resistors.

Applications

• Digital signal buffering and inversion in microcontroller interface circuits.
• Level translation between different logic voltage domains in mixed-signal systems.
• Signal conditioning for high-speed data transmission lines.

Procurement Notes

Verify the specific suffix 'PWT' confirms the tape-and-reel packaging format required for your automated pick-and-place equipment. Ensure the order quantity aligns with standard reel sizes to avoid partial reel handling issues. Confirm that the RoHS compliance status meets your environmental regulatory requirements before finalizing procurement.

Selection Notes

Select this component when six inverting buffers are required in a compact surface-mount footprint. It is appropriate for designs needing operation at supply voltages as low as 2 V or up to 6 V. Consider the -55 °C to +125 °C temperature range if the application involves harsh industrial environments or wide thermal variations.

Part Context

This part belongs to the Texas Instruments CD74HC series of high-speed CMOS logic devices. The HC designation indicates compatibility with standard CMOS performance levels while offering faster switching speeds than legacy 4000-series logic. The device is functionally compatible with other industry-standard hex inverting buffers, facilitating design portability across different manufacturers.

Replacement Considerations

Compatible substitutes include CD74HC4049PW and CD74HC4049M96. Verify pinout compatibility and electrical specifications match before substitution. Note that suffixes may indicate differences in packaging or manufacturing revisions rather than functional changes.
