74HC541DB,118

Overview

The Nexperia 74HC541DB,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 a SO20 plastic small outline package (SOT163-1) with 20 leads. Key electrical characteristics include a propagation delay of up to 115 ns at 2.0 V and 20 ns at 6.0 V. Input clamp diodes allow interfacing with voltages exceeding VCC using current limiting resistors.

Feature Summary

• Features two active-low output enable inputs for controlling high-impedance OFF-states.
• Provides high noise immunity and low power CMOS dissipation.
• Includes input clamp diodes to facilitate interface with voltages higher than the supply voltage.
• Offers robust latch-up performance exceeding 100 mA per JESD 78 Class II Level B.

Applications

• Memory address buffering
• Carry driving
• Clock drivers

Procurement Notes

Verify the specific suffix 'DB' corresponds to the SO20 (SOT163-1) package variant when sourcing. Confirm that the ordering code includes ',118' to ensure correct reel packaging specifications. Cross-reference the manufacturer part number against the latest datasheet revision to validate pinout compatibility and operating temperature ranges before finalizing procurement orders.

Selection Notes

Select this component for applications requiring wide supply voltage flexibility between 2.0 V and 6.0 V. Ensure the design accommodates the specified propagation delays and transition times under the target load capacitance conditions. Verify that the required logic levels match the CMOS input specifications defined in the static characteristics table for the chosen supply voltage.

Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. It is functionally compatible with other standard octal buffers but offers specific package and thermal characteristics defined by the SO20 form factor. The device is designed to meet JEDEC standards for operation across varying supply voltage ranges.

Replacement Considerations

Direct pin-compatible replacements include the 74HCT541 variants for TTL-level input requirements or other manufacturers' 74HC541 equivalents. Verify that substitute parts support the same SO20 package dimensions and thermal derating curves if replacing in existing designs.
