74HCT366N,652

Overview

The 74HCT366N,652 is a hex inverting buffer and line driver manufactured by NXP Semiconductors. It features six independent channels with three-state outputs controlled by active-low enable inputs (OE1 and OE2). The device operates within a supply voltage range of 4.5 V to 5.5 V and utilizes TTL-compatible input levels. It is housed in a 16-lead plastic dual in-line package (DIP16) and supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Provides inverted signal buffering and line driving capabilities for digital logic circuits
• Features three-state outputs that enter a high-impedance OFF-state when enabled inputs are HIGH
• Includes input clamp diodes to allow interfacing with voltages exceeding the supply rail

Applications

• Memory address decoding systems requiring bus isolation
• Clock distribution networks utilizing buffered signals
• Control signal routing in industrial automation equipment

Procurement Notes

Verify the specific manufacturer designation as Nexperia or NXP Semiconductors due to historical business transitions. Confirm the DIP16 package variant matches the required footprint. Ensure the HCT logic family compatibility aligns with the target system's voltage thresholds before finalizing procurement specifications.

Selection Notes

Select this component when inverted output states are required for bus management applications. The HCT series ensures direct compatibility with standard TTL logic families without additional level shifting. Verify that the thermal dissipation requirements remain within the specified limits for the chosen ambient operating conditions.

Part Context

This part belongs to the 74HCT366 series of hex buffers and line drivers. It serves as the functional inverse of the non-inverting 74HCT365 model. The device is designed for general-purpose digital logic applications requiring robust signal transmission and bus control capabilities across wide temperature ranges.

Replacement Considerations

The 74HC366N,652 is functionally identical except for CMOS input levels rather than TTL levels.
