74HC366D,652

Overview

The Nexperia 74HC366D,652 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 supports an ambient temperature range from -40 °C to +125 °C. The device utilizes a 16-lead SOIC plastic small outline package (SOT109-1). Key electrical characteristics include a maximum propagation delay of 26 ns at 6.0 V and a typical power dissipation capacitance of 30 pF per buffer.

Feature Summary

• Provides six independent inverting buffers with high-noise immunity and low CMOS power dissipation.
• Features three-state outputs that assume a high-impedance OFF-state when output enable inputs are HIGH.
• Includes input clamp diodes to allow interfacing with voltages exceeding VCC using current-limiting resistors.

Applications

• Driving bus lines or other loads requiring three-state control.
• Clock drivers for buffering and distribution.
• Memory address and data register drives.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm package type and temperature grade. Confirm RoHS compliance and halogen-free status via official datasheets before integration. Ensure design margins account for the specified absolute maximum ratings to prevent permanent damage.

Selection Notes

Select this component for applications requiring hex inverting buffers with three-state capability. Verify that the system logic levels match the HC series specifications. Consider the operating temperature range and supply voltage requirements to ensure compatibility with the intended environment and power rails.

Part Context

This part belongs to the 74HC/HCT family of high-speed CMOS logic devices manufactured by Nexperia. The 'D' suffix indicates the SOIC-16 package, while '652' denotes the specific tape-and-reel packaging configuration. It is functionally compatible with industry-standard 74HC366 definitions.

Replacement Considerations

Direct substitutes include the 74HCT366D,652 for TTL-compatible input levels. Other manufacturers producing JEDEC-compliant 74HC366 devices in SOIC-16 packages may serve as alternatives if pinout and electrical parameters align.
