74HC27N,652

Overview

The 74HC27N,652 is a triple 3-input NOR gate manufactured by NXP Semiconductors. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device complies with JEDEC standard no. 7A and features input clamp diodes for interfacing with voltages exceeding VCC. Static characteristics specify high-level output voltage (VOH) of at least 3.7 V at IO = -5.2 mA and VCC = 6.0 V, and low-level output voltage (VOL) of maximum 0.4 V at IO = 5.2 mA and VCC = 6.0 V. Dynamic performance includes a propagation delay (tpd) of 8 ns typ at VCC = 5.0 V with CL = 15 pF.

Feature Summary

• Complies with JEDEC standard no. 7A
• Includes input clamp diodes for over-voltage interfacing
• ESD protection exceeds 2000 V per HBM JESD22-A114F

Applications

• Digital logic circuits requiring triple 3-input NOR functionality
• Industrial applications operating in extended temperature ranges
• General-purpose logic systems compatible with CMOS levels

Procurement Notes

Verify the specific ordering suffix '652' against current NXP documentation to confirm package type and tape-and-reel specifications. Confirm that the DIP14 plastic dual in-line package matches the design requirements. Check for any recent product status changes or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a triple 3-input NOR gate is required with wide supply voltage flexibility between 2.0 V and 6.0 V. Ensure the application environment stays within the specified -40 °C to +125 °C operating range. Verify that the CMOS input level compatibility aligns with the driving circuitry standards used in the system design.

Part Context

This part belongs to the 74HC series of logic devices, specifically the 74HC27 family which provides three independent 3-input NOR gates. It is designed for general-purpose digital applications and offers robust ESD protection and compliance with industry standards. The DIP14 package facilitates through-hole mounting on printed circuit boards.

Replacement Considerations

Direct replacements include other 74HC27 variants from NXP or equivalent manufacturers offering identical logic function and pinout. Verify package compatibility and electrical specifications match the original design constraints.
