74HC7266N,652

Overview

The 74HC7266N,652 is a quad 2-input EXCLUSIVE-NOR gate manufactured by Nexperia (formerly NXP). It utilizes high-speed Si-gate CMOS technology and complies with JEDEC standard no. 7A. The device features active push-pull outputs and is pin-compatible with low power Schottky TTL (LSTTL). Key electrical parameters include a typical propagation delay of 11 ns at VCC = 5 V with CL = 15 pF, an input capacitance of 3.5 pF, and a power dissipation capacitance per gate of 17 pF. Operating supply voltage ranges from 2.0 V to 6.0 V.

Feature Summary

• Provides quad 2-input EXCLUSIVE-NOR logic function with active push-pull output capability.
• High-speed Si-gate CMOS construction ensures compatibility with low power Schottky TTL (LSTTL) pinouts.
• Complies with JEDEC standard no. 7A specifications for digital integrated circuits.

Applications

• Digital logic circuit design requiring EXCLUSIVE-NOR functionality.
• Systems necessitating pin-compatible replacement for LSTTL components.
• CMOS-based signal processing applications.

Procurement Notes

Verify the manufacturer origin, as the component was originally produced by Philips Semiconductors and later NXP, now Nexperia. Confirm the package type matches the required DIP-14 configuration. Ensure the ordering suffix aligns with specific tape-and-reel or tube packaging requirements if applicable. Check for RoHS compliance status relative to current manufacturing standards.

Selection Notes

Select this component when a quad 2-input EXCLUSIVE-NOR gate is required within a CMOS logic family. It is suitable for designs needing LSTTL pin compatibility. Consider the operating voltage range of 2.0 V to 6.0 V and the propagation delay characteristics for timing constraints. Verify that the standard output capability meets the load requirements of the downstream circuitry.

Part Context

The 74HC7266 belongs to the 74HC series of high-speed CMOS logic devices. Originally specified by Philips Semiconductors in December 1990, it serves as a standard SSI logic gate. The series is known for low power consumption and high noise immunity while maintaining speed comparable to older TTL technologies.

Replacement Considerations

Direct pin-compatible substitutes include other 74HC7266 variants from different manufacturers adhering to JEDEC standard no. 7A. Ensure any replacement maintains the same quad 2-input EXCLUSIVE-NOR function and active push-pull output structure.
