74LV541ATPWJ

Overview

The Nexperia 74LV541ATPWJ is an octal buffer and line driver featuring three-state outputs, designed for operation within a supply voltage range of 4.5 V to 5.5 V. It incorporates TTL-compatible inputs with Schmitt-trigger action to tolerate slower input transitions. The device includes dedicated IOFF circuitry that disables outputs during partial power-down conditions to prevent damaging backflow currents. It supports mixed-mode voltage operations across all ports and provides latch-up performance exceeding 250 mA per JESD 78 Class II standards.

Feature Summary

• Features two active-low output enable inputs (OE1 and OE2) for independent control of the three-state outputs.
• Includes IOFF circuitry to disable outputs and prevent backflow current when the device is powered down.
• Provides direct interface compatibility with TTL logic levels.

Applications

• Partial power-down applications requiring protection against backflow currents
• Mixed-mode voltage environments utilizing TTL-to-5V translation
• High-speed data buffering with controlled rise and fall times

Procurement Notes

Verify the specific ordering suffix 'J' against official Nexperia documentation to confirm packaging details and reel specifications. Ensure the procurement channel sources authentic Nexperia components to guarantee compliance with the specified operating temperatures and electrical characteristics outlined in the product data sheet.

Selection Notes

Select this component for designs requiring an 8-bit buffer with three-state outputs operating at 5 V. It is suitable for applications needing TTL input compatibility and robust noise immunity via Schmitt triggers. Verify that the system operates within the 4.5 V to 5.5 V supply range and requires the TSSOP20 package form factor.

Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices manufactured by Nexperia. It functions as an octal buffer/line driver with three-state outputs. The PWJ designation indicates a specific tape-and-reel packaging configuration within the TSSOP20 plastic thin shrink small outline package family.

Replacement Considerations

Consult official Nexperia cross-reference lists for verified substitutes. Generic equivalents may lack the specific IOFF circuitry or exact timing characteristics required for partial power-down safety.

FAQ

How does the device handle partial power-down scenarios?

The integrated IOFF circuitry automatically disables the outputs, preventing potentially damaging backflow currents through the device when it is powered down.

What is the function of the OE1 and OE2 pins?

OE1 and OE2 are active-low output enable inputs. A HIGH level on either pin causes the associated outputs to assume a high-impedance OFF-state.
