Procurement Notes
Verify the component matches the Philips/NXP 74HC7266 product specification dated December 1990. Confirm the package type corresponds to the SO16 outline referenced in the IC06 package information documents. Ensure the device meets the JEDEC standard no. 7A requirements for HC series logic. Check that the ordering suffix aligns with the specific tape and reel or tube packaging details provided by the manufacturer.
Selection Notes
Select this component when a quad EXCLUSIVE-NOR gate is required in a design utilizing HC series CMOS technology. It is suitable for applications needing compatibility with LSTTL pinouts. Consider the 2.0 V to 6.0 V operating voltage range and the standard output drive capability. Verify that the propagation delay and power dissipation characteristics meet the system timing and thermal constraints.
Part Context
The 74HC7266 belongs to the 74HC/HCT/HCU/HCMOS Logic Family. It is part of the IC06 file category for integrated circuits. The device is manufactured by Philips Semiconductors, now NXP Semiconductors. It serves as a digital logic gate within the broader portfolio of high-speed CMOS logic devices designed for various electronic applications.
Replacement Considerations
