74HCT366DB,118

Overview

The 74HCT366DB,118 is a hex inverting buffer/line driver with 3-state outputs controlled by two active LOW output enable inputs (OE1, OE2). It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL-level input compatibility, CMOS low power dissipation, and high noise immunity. Inputs include clamp diodes for interfacing with voltages exceeding VCC. The component is housed in a 16-lead SSOP plastic package.

Feature Summary

• Hex inverting buffer/line driver with 3-state outputs
• TTL-level input compatibility
• Dual active LOW output enable control
• Extended industrial temperature operation

Applications

• Bus driving applications requiring signal inversion
• Line drivers for data transmission lines
• Interface circuits between logic families
• High-noise environments requiring robust buffering

Procurement Notes

Verify the specific ordering suffix 'DB' corresponds to the SSOP16 package variant. Confirm that the manufacturer designation aligns with current Nexperia product portfolios, as NXP Semiconductor branding may appear on legacy documentation. Ensure the component meets the required automotive or industrial qualification standards if applicable to the design.

Selection Notes

Select this component when inverting functionality is required alongside bus driving capabilities. The HCT series ensures direct compatibility with TTL logic levels while maintaining CMOS performance characteristics. Verify that the dual enable pin configuration fits the system's control architecture and that the SSOP package dimensions are suitable for the PCB layout constraints.

Part Context

This part belongs to the 74HCT366 family of hex buffers and line drivers. It is functionally similar to non-inverting variants but provides inverted outputs. The 'DB' suffix indicates the SSOP16 package type. The device is manufactured by Nexperia, continuing the lineage of standard logic components originally associated with NXP Semiconductor.

Replacement Considerations

Direct functional substitutes include the 74HC366 series for HC-level input requirements. For identical HCT specifications, verify availability of other package variants such as PW (TSSOP) or D (SO16) from the same manufacturer.
