TC74HC4049AF(EL,F)

Overview

The TC74HC4049AF(EL,F) is a CMOS digital integrated circuit manufactured by Toshiba Semiconductor and Storage. It functions as an inverting buffer with six independent channels, each handling one bit of data. The device operates within a supply voltage range of 2 V to 6 V and supports surface mount installation in a 16-SOIC package. It features push-pull outputs and is designed for operation across a temperature range of -40°C to +85°C.

Feature Summary

• Provides six independent inverting buffer channels for signal inversion and level shifting.
• Features push-pull output stages capable of driving loads directly without external pull-up or pull-down resistors.
• Operates reliably across a wide industrial temperature range from -40°C to +85°C.

Applications

• Level shifting between logic families operating at different voltage levels.
• Signal inversion in digital logic circuits.
• Buffering signals on printed circuit boards to improve drive capability.

Procurement Notes

Verify the specific suffix EL,F against the manufacturer's current datasheet to confirm pinout and electrical characteristics match your design requirements. Confirm RoHS compliance status and check for obsolescence notices, as availability may vary. Ensure the 16-SOIC footprint matches your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when six independent inverting buffers are required within a single package. It is suitable for applications needing voltage translation between 2V and 6V domains. Consider the 16-SOIC package size and thermal performance if high-density mounting is necessary. Verify that the inverting function aligns with the logical requirements of the target circuit design.

Part Context

This part belongs to the Toshiba 74HC series of high-speed CMOS logic devices. The 74HC family is known for compatibility with standard TTL logic levels while offering lower power consumption. The TC74HC4049 specifically addresses the need for multiple inverting buffers in compact surface-mount designs, serving as a fundamental building block for complex digital systems.

Replacement Considerations

Direct replacements include other manufacturers' 74HC4049 variants in 16-SOIC packages. Verify pin compatibility and electrical specifications such as output current and propagation delay. Cross-reference with equivalent parts like the SN74HC4049 or similar industry-standard alternatives ensuring functional equivalence.
