74HCT4002DB,112

Inverter Gates Overview

The Nexperia 74HCT4002DB,112 is a dual 4-input NOR gate from the 74HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device complies with JEDEC standard JESD7A and features low-power dissipation. Inputs adhere to TTL levels, while outputs provide CMOS-compatible drive. ESD protection exceeds 2000 V (HBM) and 200 V (MM). It is housed in an SSOP14 plastic shrink small outline package (SOT337-1) with 14 leads.

Inverter Gates Selection Notes

Select this component when TTL-level inputs must interface directly with CMOS NOR logic without external pull-up resistors or level shifters. The SSOP14 package offers a compact footprint suitable for space-constrained PCB layouts. Ensure the design environment remains within the specified -40 °C to +125 °C temperature range to maintain guaranteed static and dynamic performance characteristics.

Inverter Gates Part Context

This part belongs to the 74HCT series, which bridges the gap between older TTL standards and modern CMOS technologies. Unlike the 74HC variant, the HCT series is specifically optimized for 5 V operation with TTL-compatible input thresholds. This allows seamless integration into legacy systems or mixed-voltage environments where direct connection to TTL outputs is required.

Inverter Gates Replacement Considerations

The 74HC4002DB,112 serves as a pin-compatible alternative but requires CMOS-level input signals rather than TTL levels. Designers must verify that upstream drivers can meet the higher VIH threshold of the HC series before substituting.
