CD74HC4049EG4

Overview

The CD74HC4049EG4 is a high-speed CMOS hex inverting buffer manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -55 °C to +125 °C. The device features push-pull outputs and is housed in a 16-pin SOIC package with a width of 3.90 mm. It belongs to the 74HC logic series and provides six independent inverting buffer channels.

Feature Summary

• High-speed CMOS technology for efficient signal buffering
• Six independent inverting buffer channels
• Push-pull output configuration
• Wide operating temperature range

Applications

• Signal level translation between different logic families
• Buffering digital signals in high-speed circuits
• Inverting logic signals in microcontroller interfaces

Procurement Notes

Verify the specific suffix 'EG4' against the manufacturer's current datasheet to confirm RoHS compliance status and package dimensions. Ensure the ordering part number matches the exact pinout and electrical specifications required for your design, as suffixes may indicate variations in packaging or environmental compliance that do not alter the core function.

Selection Notes

Select this component when a hex inverting buffer is required for high-speed CMOS applications. It is suitable for designs needing signal inversion with push-pull outputs across a wide voltage range. Consider the 16-SOIC package constraints and ensure thermal management aligns with the specified operating temperature limits for reliable performance.

Part Context

This component is part of the Texas Instruments 74HC series, which offers high-speed CMOS logic functions. The CD74HC4049 specifically provides hex inverting buffers, distinguishing it from non-inverting counterparts like the CD74HC4050. It is designed for general-purpose digital signal processing tasks requiring robust buffering capabilities.
