74HC4049PW,118

Overview

The Nexperia 74HC4049PW,118 is a hex inverting HIGH-to-LOW level shifter housed in a TSSOP16 package. It operates on a supply voltage range of 2.0 V to 6.0 V with inputs tolerant up to 15 V. The device features six channels with propagation delays ranging from 8 ns to 28 ns depending on voltage. It supports an ambient temperature range of -40 °C to +125 °C and includes ESD protection exceeding 2000 V (HBM).

Feature Summary

• Hex inverting logic configuration for signal inversion.
• Overvoltage tolerant inputs capable of handling signals up to 15 V.
• Designed specifically for HIGH-to-LOW level shifting applications.

Applications

• Level shifting between different voltage domains.
• Signal inversion in digital circuits.
• Interfacing high-voltage logic to low-voltage systems.

Procurement Notes

Verify the specific ordering suffix '118' corresponds to the TSSOP16 package variant when sourcing. Confirm that the component meets the required operating temperature range of -40 °C to +125 °C for your specific application environment. Ensure input voltages do not exceed the absolute maximum ratings defined in the datasheet to prevent permanent damage.

Selection Notes

Select this component when interfacing logic families requiring voltage translation from higher levels down to lower CMOS levels. The wide supply voltage range allows flexibility in power design. Consider the TSSOP16 package dimensions if board space is constrained. Verify that the overvoltage tolerance matches the source signal amplitude.

Part Context

This part belongs to the 74HC series of CMOS logic devices manufactured by Nexperia. It is functionally related to other inverters but distinguished by its specific overvoltage tolerance capabilities. The PW suffix indicates the plastic thin shrink small outline package type used for surface mount assembly.

Replacement Considerations

Check for equivalent parts within the same logic family that offer similar overvoltage tolerance. Verify pin compatibility and package dimensions before substitution. Ensure any replacement maintains the required electrical characteristics for the intended voltage levels.

FAQ

What is the maximum input voltage the 74HC4049 can tolerate?

The inputs are overvoltage tolerant up to 15 V, allowing it to interface with higher voltage logic levels.

Does the 74HC4049 provide non-inverting output?

No, it is a hex inverter, meaning each channel provides an inverted output relative to its input.
