74LV541N,112

Overview

The NXP USA Inc. 74LV541N,112 is an octal buffer and line driver featuring non-inverting outputs with three-state control. It operates on a supply voltage range of 1.0 V to 3.6 V and accepts TTL input levels between 2.7 V and 3.6 V. The device utilizes low-voltage Si-gate CMOS technology and is pin-compatible with 74HC541 and 74HCT541 variants. It provides two active-low output enable inputs (OE1 and OE2) to manage high-impedance states. The component supports operation from -40 °C to +125 °C and includes ESD protection exceeding 2000 V HBM. It is housed in a DIP20 plastic dual in-line package.

Feature Summary

• Octal non-inverting buffer/line driver with three-state outputs controlled by OE1 and OE2 inputs
• Optimized for low voltage applications with a wide supply range from 1.0 V to 3.6 V
• Compatible with TTL input levels when the supply voltage is between 2.7 V and 3.6 V
• High electrostatic discharge protection capability exceeding 2000 V under Human Body Model conditions

Applications

• Bus driver implementations in mixed voltage environments

Procurement Notes

Verify the specific ordering suffix '112' against current manufacturer documentation to confirm availability and exact package specifications. Confirm that the DIP20 form factor meets the target PCB layout requirements. Check for any recent product change notices or end-of-life announcements directly from NXP Semiconductors before finalizing procurement plans.

Selection Notes

Select this component when an octal buffer with three-state capability is required for low-voltage logic interfaces. Ensure the design environment supports the specified temperature range of -40 °C to +125 °C. Verify that the system power supply remains within the 1.0 V to 3.6 V operational limits to maintain signal integrity and performance specifications.

Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices manufactured by NXP Semiconductors. The 74LV541 specifically functions as an octal buffer/line driver. It serves as a direct replacement for similar octal buffers in designs requiring compatibility with HC/HCT logic standards while operating at lower supply voltages.

Replacement Considerations

The 74LV541N,112 is functionally compatible with the 74HC541 and 74HCT541 regarding pinout and basic logic operations. Designers should verify voltage level compatibility, particularly noting the 1.0 V to 3.6 V operating range of the LV series compared to standard HC/HCT specifications.
