SN74HC02QPWREP

Overview

The SN74HC02QPWREP is a military-enhanced quad two-input positive-NOR gate manufactured by Texas Instruments. It belongs to the HC logic series and operates within a supply voltage range of 2 V to 6 V. The device features four independent NOR gates with eight inputs and four outputs, housed in a TSSOP-14 package. Key electrical parameters include a propagation delay of 8 ns, low-level output current of 5.2 mA, and high-level output current of -5.2 mA. It supports surface mount installation and functions reliably across an operating temperature range from -40°C to +125°C.

Procurement Notes

Verify the complete part number including the QPWR suffix to confirm military enhancement status and specific tape-and-reel packaging configuration. Ensure the procurement documentation explicitly references the SN74HC02QPWREP designation to distinguish it from standard commercial variants. Confirm RoHS compliance details and check for any specific agency certification requirements relevant to defense or aerospace supply chains before finalizing orders.

Selection Notes

Select this component when designing circuits that require robust NOR logic functionality under harsh environmental conditions. The wide voltage range allows flexibility in power supply design, while the TSSOP-14 package offers space-efficient surface mounting. Consider the 8 ns propagation delay for timing constraints and ensure the thermal management strategy accommodates the extended temperature range capabilities specified for military applications.

Part Context

This part is a member of the SN74HC02 family, specifically tailored for military specifications. It provides quad two-input NOR gates in a compact TSSOP-14 package. The device is designed for high-reliability applications where standard commercial parts may not suffice. It complements other logic families by offering robust performance in challenging operational environments.
