74HC541D,653

Overview

The Nexperia 74HC541D,653 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 utilizes CMOS technology for low power dissipation. The device includes two active-low output enable inputs (OE1 and OE2) that force outputs into a high-impedance state when asserted HIGH. Inputs are equipped with clamp diodes to facilitate interfacing with voltages exceeding VCC using current limiting resistors. The component is housed in a 20-lead SO plastic small outline package (SOT163-1).

Feature Summary

• Octal non-inverting buffer/line driver with three-state outputs controlled by two independent enable inputs.
• CMOS construction providing wide supply voltage operation from 2.0 V to 6.0 V and low power dissipation.
• Input clamp diodes allow safe interfacing to input voltages higher than the supply voltage when used with current limiting resistors.

Applications

• High-noise immunity signal buffering in digital systems.
• Line driving applications requiring isolation via three-state control.
• Voltage level translation between logic families utilizing clamp diode protection.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range specifications. Ensure compatibility with system requirements regarding ESD protection levels and latch-up performance standards before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring eight-channel non-inverting buffering with tri-state capability. Confirm that the operating environment falls within the specified -40 °C to +125 °C temperature range. Verify that the application voltage does not exceed the absolute maximum ratings defined in the datasheet.

Part Context

This part belongs to the 74HC/HCT logic family manufactured by Nexperia. It serves as an octal buffer variant within the broader series of standard logic integrated circuits designed for general-purpose digital applications across various industrial and consumer electronics platforms.

Replacement Considerations

The 74HCT541D,653 is a compatible alternative within the same product family offering TTL-compatible input levels instead of CMOS levels. Both devices share identical pinouts and functional descriptions but differ in input threshold voltage specifications.
