CD74HC4050PW

Overview

The CD74HC4050PW is a hex non-inverting buffer manufactured by Texas Instruments, belonging to the HC logic family. It features six independent input lines and six corresponding output lines within a single package. The device operates on a supply voltage range of 2 V to 6 V and utilizes CMOS output technology. It is housed in a 16-pin TSSOP surface-mount package. The component supports an operating temperature range from -55°C to +125°C. Propagation delay varies with voltage, specified at 85 ns at 2 V, 17 ns at 4.5 V, and 14 ns at 6 V. Static current is typically 2 uA, with a maximum high-level output current of -5.2 mA and low-level output current of 5.2 mA.

Feature Summary

• Provides six independent non-inverting buffering channels for signal integrity maintenance.
• Capable of functioning as a high-to-low voltage level converter for logic interfacing.
• Features modified input protection structures designed to withstand negative electrostatic discharge events.

Applications

• Level shifting between high-voltage logic inputs and lower-voltage CMOS systems.
• General-purpose buffering for digital signal lines in embedded circuits.
• Bus driving applications requiring isolation between source and load.

Procurement Notes

Verify the specific suffix 'PW' confirms the TSSOP-16 package type during sourcing. Ensure the order quantity matches the reel or cut-tape availability requirements. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the manufacturer date code against project lifecycle requirements to avoid obsolescence risks associated with older production runs.

Selection Notes

Select this component when six buffered outputs are required in a compact surface-mount form factor. It is suitable for designs needing operation across a wide industrial temperature range. Consider its voltage translation capability if interfacing 15V signals to 5V logic domains. Verify that the propagation delay specifications meet the timing constraints of the target application circuit.

Part Context

This part belongs to the CD74HC4050 series of high-speed CMOS logic devices. It serves as the commercial-grade counterpart to the military-grade CD54HC4050. The device is part of Texas Instruments' broader portfolio of buffer and line driver integrated circuits designed for general-purpose digital logic applications.

Replacement Considerations

CD74HC4050PWR: Same logical function and pinout but packaged in TSSOP-16 with tape-and-reel packaging instead of tube.
