74HC366D,653

Overview

The Nexperia 74HC366D,653 is a hex inverting buffer and line driver featuring three-state outputs controlled by active LOW enable inputs (OE1, OE2). 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 input clamp diodes to facilitate interfacing with voltages exceeding VCC. It provides high noise immunity and robust latch-up performance compliant with JESD 78 Class II Level B standards.

Feature Summary

• Hex inverting buffer/line driver with three-state outputs
• Wide supply voltage range from 2.0 V to 6.0 V
• Input clamp diodes allow interfacing to voltages above VCC
• High noise immunity and robust latch-up protection

Applications

• Data bus driving applications requiring signal inversion
• Memory address decoding circuits
• Clock distribution networks
• General-purpose digital logic buffering

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74HC366 series is available in SO16 (SOT109-1) and TSSOP16 (SOT403-1) configurations. Confirm temperature range requirements against the datasheet specifications before finalizing procurement orders.

Selection Notes

Select this component when an inverting function is required alongside three-state control capabilities. Ensure the system voltage falls within the 2.0 V to 6.0 V operating range. Consider the HC logic family for standard CMOS compatibility and low static power consumption compared to TTL alternatives.

Part Context

This part belongs to the 74HC/HCT logic family, widely used for general-purpose digital applications. The 74HC366 specifically addresses scenarios needing signal inversion and bus isolation. It complements non-inverting drivers like the 74HC244 and other buffers within the same manufacturer's portfolio.

Replacement Considerations

Direct functional replacements include the 74HCT366D variant for TTL-compatible input levels. Other manufacturers' equivalents such as SN74HC366 or MC74HC366 may be considered if pinout and electrical characteristics align with the original specification.
