74VHCT541PW,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74VHCT541PW,118 is an octal non-inverting buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes TTL input levels. The device provides balanced propagation delays and accepts input voltages exceeding the supply rail. It is housed in a 20-lead TSSOP plastic thin shrink small outline package (SOT360-1) and supports ambient temperatures from -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features Schmitt-trigger action on all inputs for improved noise immunity
• Outputs are controlled by two active-low output enable inputs (OE0 and OE1)
• Inputs tolerate voltages higher than the supply voltage (VCC)
• Includes ESD protection compliant with Human Body Model, Machine Model, and Charged Device Model standards

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented communications systems
• Clock buffering and distribution
• Memory module data bus drivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature rating. Confirm the logic family variant corresponds to the intended interface voltage levels. Ensure compliance with RoHS3 specifications if required by the manufacturing process. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing TTL-level signals to high-speed CMOS buses requiring three-state control. The VHCT series is appropriate for applications needing direct compatibility with standard TTL logic outputs. Consider the TSSOP package dimensions for PCB layout constraints. Evaluate power dissipation limits relative to the operating temperature range.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Nexperia 74VHC/VHCT logic family, which combines high-speed CMOS performance with low power consumption. The 74VHCT variants specifically bridge the gap between TTL and CMOS logic families by accepting TTL input thresholds while maintaining CMOS output drive capabilities. This facilitates mixed-voltage system designs without additional level-shifting components.
