74HCT366DB,118

Overview

The 74HCT366DB,118 is a hex inverting buffer/line driver with 3-state outputs controlled by active LOW output enable inputs (OE1, OE2). It belongs to the HCT logic family, featuring TTL input levels and CMOS low power dissipation. The device 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. Inputs include clamp diodes for overvoltage interfacing. The component is housed in a 16-lead SSOP package (SOT338-1) and complies with JEDEC standards JESD8C and JESD7A.

Feature Summary

• Hex inverting buffer/line driver with 3-state outputs
• TTL input levels compatible with CMOS technology
• High noise immunity and robust latch-up performance
• Wide operating temperature specification

Applications

• Bus driving applications requiring signal inversion
• Mixed 5 V and 3.3 V system interfaces
• Industrial control systems
• Telecommunications infrastructure

Procurement Notes

Verify that the specific ordering suffix ',118' corresponds to the SSOP-16 package configuration as defined in Nexperia's official documentation. Confirm that the procurement channel provides the original manufacturer's product data sheet to ensure compliance with the specified electrical characteristics and pinout definitions. Cross-reference the part number against current availability status to avoid obsolete components.

Selection Notes

Select this component when a hex inverting line driver with 3-state capability is required for TTL-to-CMOS level translation. Ensure the application environment stays within the recommended 4.5 V to 5.5 V supply voltage range. Consider the thermal derating requirements if operating near the upper temperature limit of +125 °C. Verify that the SSOP package dimensions fit the PCB layout constraints.

Part Context

This part is a member of the 74HCT series, designed for high-speed operation with TTL-compatible inputs. It serves as a functional equivalent to other hex buffers but specifically provides inverted outputs. The 'DB' designation indicates the plastic small outline SSOP package variant. It is distinct from the HC series which utilizes CMOS input levels rather than TTL thresholds.

Replacement Considerations

The 74HC366PW-Q100,118 is a functionally similar hex buffer/line driver with inverted outputs and 3-state capabilities, though it features HC logic levels instead of HCT. Verify input voltage compatibility before substitution. Other variants such as 74HCT366D are available in different packages like SO16.
