74HCT11DB,112

Overview

The Nexperia 74HCT11DB,112 is a triple 3-input AND gate integrated circuit belonging to the 74HCT logic family. 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 and includes clamp diodes on all inputs. It is housed in a 14-lead SO plastic small outline package (SOT108-1) with a body width of 3.9 mm.

Feature Summary

• Provides three independent 3-input AND logic gates within a single package.
• Features TTL-compatible input levels for direct interfacing with standard logic families.
• Includes input clamp diodes to allow the use of current limiting resistors for voltages exceeding VCC.
• Offers high noise immunity and robust latch-up performance compliant with JESD 78 Class II Level B.

Applications

• Digital logic circuits requiring multiple AND operations
• Interface modules utilizing TTL-level signaling
• General-purpose combinatorial logic designs

Procurement Notes

Verify component authenticity through authorized Nexperia distributors or official channels. Confirm that the specific ordering suffix matches the required package type and temperature rating. Ensure compliance with RoHS directives and REACH regulations prior to integration into final assemblies.

Selection Notes

Select this component when TTL-level inputs are required alongside CMOS output characteristics. Verify that the operating voltage remains strictly between 4.5 V and 5.5 V. Consider the 14-SO package dimensions for PCB layout constraints and thermal dissipation requirements during design.

Part Context

This part belongs to the 74HCT series, which bridges TTL and CMOS technologies. It shares functional similarities with the 74HC11 but differs in input threshold specifications. The 'DB' suffix indicates the SO14 package variant, distinct from TSSOP or SSOP options available in the broader product line.

Replacement Considerations

Public confirmed substitute part numbers include 74HC11D,652 and 74HCT11PW,118.
