74HC541PW,118

Overview

The Nexperia 74HC541PW,118 is an octal non-inverting buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device utilizes CMOS technology for low power dissipation and includes two active-low output enable inputs (OE1 and OE2). Inputs are equipped with clamp diodes to allow interfacing with voltages exceeding VCC when used with current limiting resistors.

Feature Summary

• Octal non-inverting buffer/line driver architecture
• Three-state outputs controlled by dual active-low enables
• CMOS construction ensuring low power consumption
• Input clamp diodes for extended voltage interfacing

Applications

• High-impedance data bus buffering
• Line driving in communication systems
• Memory address/data bus interfaces
• Clock distribution networks

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure compatibility with JEDEC standards JESD7A and JESD8C for your operating voltage. Confirm ESD protection ratings meet system requirements before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring high noise immunity and wide supply voltage flexibility. The TSSOP20 package offers space efficiency for surface-mount designs. Consider the propagation delay characteristics relative to your clock speeds and ensure thermal derating limits are respected under maximum load conditions.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. It is functionally compatible with other industry-standard octal buffers but offers specific performance metrics defined by Nexperia's manufacturing processes. The PW suffix indicates the TSSOP20 plastic thin shrink small outline package variant.

Replacement Considerations

Direct pin-compatible substitutes include the 74HCT541PW,118 for TTL-level input requirements. Other manufacturers' equivalent octal buffers may require verification of voltage levels and electrical characteristics to ensure functional parity.
