CD54HC11F3A

Inverter Gates Overview

The CD54HC11F3A is a high-speed CMOS logic gate manufactured by Harris Corporation. It contains three independent 3-input AND gates within a single package. The device utilizes a ceramic dual in-line package (CDIP) with frit sealing, designed for military and aerospace environments. It operates over an extended temperature range of -55°C to +125°C. The circuit features complementary outputs and supports standard CMOS logic levels, ensuring compatibility with other HCT/HC series components in complex digital systems.

Inverter Gates Feature Summary

• Contains three independent 3-input AND logic functions
• Utilizes hermetically sealed ceramic construction for environmental protection
• Supports operation across extended industrial and military temperature ranges

Inverter Gates Applications

• Military avionics signal processing
• Aerospace control system logic
• Harsh environment digital data gating

Inverter Gates Procurement Notes

Verify the manufacturer origin, as Harris Corporation assets were acquired by Renesas Electronics. Confirm the specific suffix 'F3A' corresponds to the correct ceramic DIP package variant. Ensure compliance with required military specifications if the application demands qualified heritage parts. Check for RoHS status, as older Harris ceramic parts may not meet modern environmental directives.

Inverter Gates Selection Notes

Select this component when hermetic sealing is mandatory for radiation or moisture resistance. Compare pinout compatibility with equivalent Texas Instruments or Renesas offerings. Verify voltage supply requirements match the HC series standards. Consider lead time availability due to the specialized nature of ceramic packaged legacy logic families.

Inverter Gates Part Context

This part belongs to the Harris CD54HCxx family of high-speed CMOS logic devices. The '54' prefix indicates military-grade temperature rating and reliability standards. The 'HC' denotes High-speed CMOS technology. The '11' identifies the specific function as triple 3-input AND gates. The 'F3A' suffix specifies the ceramic flatpack or DIP packaging configuration used in ruggedized applications.

Inverter Gates Replacement Considerations

Equivalent parts include the CD54HC11F from Texas Instruments or the HD74HC11FP from Hitachi. Verify that substitute packages maintain the same pinout and hermetic sealing requirements. Renesas Electronics now produces compatible variants under the Harris legacy branding.
