74LV541D,118

Overview

The 74LV541D,118 is an octal non-inverting buffer and line driver manufactured by NXP USA Inc. It features 3-state outputs controlled by two active-LOW enable inputs, OE1 and OE2. The device utilizes low-voltage Si-gate CMOS technology and operates within a supply voltage range of 1.0 V to 3.6 V. It is housed in a SO20 plastic small outline package (SOT163-1) with a body width of 7.5 mm. The component supports ambient temperatures from -40 °C to +125 °C and is pin and function compatible with 74HC541 and 74HCT541 devices.

Feature Summary

• Optimized for low-voltage applications with operation down to 1.0 V
• Accepts TTL input levels when supply voltage is between 2.7 V and 3.6 V
• Includes ESD protection exceeding 2000 V via Human Body Model and 200 V via Machine Model
• Features dual output enables allowing high-impedance OFF-state control

Applications

• Bus driver implementations in mixed voltage environments
• Line driving for low-voltage digital systems
• Signal buffering where TTL compatibility is required at 3.3 V logic levels

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74LV541 series includes DIP, SSOP, and TSSOP variants. Confirm the temperature grade corresponds to your operational requirements, noting that the standard range extends to +125 °C. Ensure design compliance with absolute maximum ratings regarding supply voltage and current limits to prevent device damage.

Selection Notes

Select this component when low power consumption and wide supply voltage flexibility are necessary. It serves as a direct replacement for 74HC541 and 74HCT541 in designs requiring lower operating voltages. Consider the SO20 package constraints regarding thermal derating above 70 °C if high power dissipation is anticipated in the application environment.

Part Context

This part belongs to the 74LV541 family of octal buffers and line drivers. It is designed as a low-voltage alternative to standard CMOS logic families, offering improved performance in battery-powered or low-voltage systems. The device maintains functional compatibility with higher voltage counterparts while optimizing for reduced power usage and ground bounce characteristics.

Replacement Considerations

The 74LV541D is pin-compatible with 74HC541 and 74HCT541. Verify that the target system's supply voltage falls within the 1.0 V to 3.6 V range to ensure proper functionality.
