74HCT02DB,112

Overview

The 74HCT02DB,112 is a quad 2-input NOR gate manufactured by Nexperia USA Inc. 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 input levels and includes clamp diodes on inputs for interfacing with voltages exceeding VCC. It provides high noise immunity and latch-up performance exceeding 100 mA per JESD 78 Class II Level B. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Propagation delay is typically 11 ns at 4.5 V and 9 ns at 5.0 V with 15 pF load capacitance.

Feature Summary

Quad 2-input NOR logic function
TTL-compatible input switching levels
High noise immunity and robust latch-up performance
Input clamp diodes for overvoltage tolerance

Applications

Digital signal processing logic circuits
General-purpose logic applications requiring TTL compatibility
Noise-immune digital interface designs

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the SSOP-14 package variant when sourcing. Confirm current production status as datasheet revisions may impact availability. Ensure compliance with RoHS directives and REACH regulations for the intended application environment. Cross-reference pinout requirements against the SOT108-1 outline before finalizing PCB layout.

Selection Notes

Select this component when TTL-level inputs are required in a CMOS process environment. The HCT series ensures compatibility with standard TTL logic outputs while maintaining low power dissipation characteristics. Verify that the operating voltage remains strictly within the 4.5 V to 5.5 V range to ensure correct logic threshold behavior and timing specifications.

Part Context

This part belongs to the 74HCT02 family of quad 2-input NOR gates. It shares functional similarities with the 74HC02 but utilizes different input voltage thresholds tailored for TTL systems. The DB suffix indicates the SSOP-14 surface-mount package option, distinct from SO or TSSOP variants within the same logical family.
