74HC4049N,652

Overview

The 74HC4049N,652 is a hex inverting HIGH-to-LOW level shifter manufactured by NXP Semiconductors. It features over-voltage tolerant inputs capable of withstanding up to 15 V, enabling its use in logic level conversion applications. The device operates on a single supply voltage ranging from 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. It is housed in a 16-lead plastic dual in-line package (DIP16) conforming to the SOT38-4 outline.

Feature Summary

• Hex inverter architecture designed for HIGH-to-LOW level shifting
• Input over-voltage tolerance up to 15 V
• ESD protection exceeding 2000 V per Human Body Model standard

Applications

• Logic level translation between high and low voltage domains
• Battery backup circuit interfacing
• CMOS to TTL level translation

Procurement Notes

Verify the specific ordering suffix against current NXP documentation to confirm package type and temperature grade. Confirm RoHS compliance status as required by your manufacturing standards. Ensure the DIP16 package variant matches your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when interfacing higher voltage logic systems with lower voltage CMOS circuits. The 15 V input tolerance allows direct connection to sources exceeding the VCC supply. Verify that the propagation delay characteristics meet the timing requirements of your specific application at the intended operating voltage.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices. It functions specifically as a buffer and line driver for level shifting. The manufacturer offers multiple package options including SO16, SSOP16, and TSSOP16 for different mounting requirements.

Replacement Considerations

Compatible alternatives include the 74HC4049D, 74HC4049DB, and 74HC4049PW. These variants share identical electrical specifications but differ in physical package dimensions and mounting styles.
