CD74HC4049PWR

Overview

The CD74HC4049PWR is a high-speed CMOS logic hex buffer manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports surface mount installation in a TSSOP-16 package. The device functions as an inverting buffer with push-pull outputs, designed for applications requiring signal level translation between CMOS and TTL logic families. It features a wide operating temperature range from -55 °C to +125 °C.

Feature Summary

• Provides six independent inverting buffer channels for signal conditioning
• Capable of translating voltage levels between CMOS and TTL logic standards
• Features push-pull output stages for robust drive capability

Applications

• CMOS to TTL level translation circuits
• Signal buffering in digital logic systems
• Voltage level shifting interfaces

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-16 surface-mount package configuration. Confirm that the ordering part number matches the required inverting buffer functionality rather than non-inverting variants. Ensure compatibility with the intended PCB footprint and soldering profile for thin-shrink small-outline packages.

Selection Notes

Select this component when six-channel inverting buffering is required alongside CMOS-to-TTL level translation capabilities. The TSSOP-16 package offers a compact solution for space-constrained designs. Verify that the input voltage levels align with the target logic family requirements to ensure proper interface operation without additional external components.

Part Context

This component belongs to the Texas Instruments CD74HC4049 series of high-speed CMOS logic devices. The series provides hex buffers available in both inverting and non-inverting configurations. The HC designation indicates high-speed CMOS technology, offering performance comparable to standard TTL while maintaining low power consumption typical of CMOS devices.

Replacement Considerations

CD74HC4049PW (PDIP-14 equivalent function) and CD74HC4049M (SOIC-14 equivalent function). Verify pinout compatibility and package dimensions before substitution.
