74HCT541PW,118

Overview

The Nexperia 74HCT541PW,118 is an octal non-inverting buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL-level input signals. The device incorporates two active-low output enable inputs (OE1 and OE2) that force the outputs into a high-impedance state when asserted HIGH. Inputs include clamp diodes for interfacing with voltages exceeding VCC. It is housed in a 20-lead TSSOP plastic package.

Feature Summary

• Octal non-inverting buffer configuration with three-state outputs
• Dual active-low output enables for independent control
• TTL-compatible input logic levels
• Input clamp diodes for overvoltage protection

Applications

• High-speed data bus buffering
• Line driving applications requiring isolation
• Memory address/data bus drivers
• Clock distribution networks

Procurement Notes

Verify the specific ordering suffix ',118' corresponds to the standard tape-and-reel packaging format required by your automated assembly equipment. Confirm that the 20-TSSOP footprint matches your PCB design guidelines. Ensure the component meets RoHS3 compliance standards for your target market regulations before finalizing procurement orders.

Selection Notes

Select this component when TTL-level compatibility is required at 5 V logic systems. The dual enable pins provide flexible control over bus directionality. Verify that the 6 mA output drive capability satisfies the load requirements of your connected circuitry. Consider the thermal derating characteristics if operating near the maximum temperature limits.

Part Context

This part belongs to the 74HCT series of CMOS logic devices, designed specifically for operation with 5 V power supplies while maintaining compatibility with older TTL logic families. The 'PW' designation indicates the TSSOP20 package variant, which offers a compact surface-mount solution compared to traditional SOIC packages.

Replacement Considerations

The 74HC541PW,118 serves as a functional substitute but requires CMOS-level input signals rather than TTL levels. Other package variants such as the 74HCT541D,118 offer identical electrical performance in an SOIC20 housing.
