74HCT7541PW,118

Overview

The Nexperia 74HCT7541PW,118 is an octal Schmitt trigger buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device utilizes a TSSOP20 (SOT360-1) package with 20 leads. It includes two active-low output enable inputs (OE1, OE2) and eight data inputs equipped with clamp diodes for interfacing voltages exceeding VCC.

Feature Summary

• Schmitt-trigger inputs convert slowly changing signals into sharply defined jitter-free outputs
• Two independent active-low output enables control high-impedance OFF-states
• Input clamp diodes allow current limiting resistor usage for voltages above VCC
• Non-inverting logic function with CMOS low power dissipation

Applications

• Octal bus interface systems
• Clock distribution buffering
• Line driving applications requiring noise immunity

Procurement Notes

Verify the specific ordering suffix '118' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the TSSOP20 body width matches the target PCB footprint design constraints. Ensure the HCT logic family compatibility aligns with the TTL input levels of the destination circuitry.

Selection Notes

Select this component when TTL-compatible input thresholds are necessary alongside Schmitt trigger noise filtering capabilities. The HCT series ensures direct compatibility with standard TTL logic families while maintaining CMOS power efficiency. Verify that the 3-state output configuration meets the bidirectional bus requirements of the system design.

Part Context

This part belongs to the Nexperia 74HCT7541 product family, which shares functional specifications with the 74HC7541 variant but differs in input threshold levels. The PW suffix indicates the TSSOP20 plastic thin shrink small outline package, distinguishing it from the SO20 D package variant.

Replacement Considerations

The SN74AC7541PWR from Texas Instruments is listed as a substitute option.
