54ACTQ32/QCA

Overview

The Rochester Electronics LLC 54ACTQ32/QCA is a high-speed CMOS quad 2-input OR gate manufactured using advanced CHMOS III technology. It features a 14-pin ceramic DIP package with glass-sealed construction, ensuring reliability in harsh environments. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a wide temperature range from -55 °C to 125 °C. It provides four independent logic channels, each accepting two inputs. The component utilizes parallel access and is designed for applications requiring robust digital signal processing under extreme conditions.

Feature Summary

• Advanced CHMOS III technology ensures high-speed operation and low power consumption
• Ceramic DIP package with glass-sealed construction for enhanced environmental durability
• Wide operating temperature range suitable for military and industrial applications
• Quad configuration providing four independent 2-input OR logic gates

Applications

• Military avionics systems requiring radiation-hardened or high-reliability logic components
• Industrial control systems operating in extreme temperature environments
• Aerospace communication equipment needing robust digital signal routing
• Defense electronics utilizing ceramic-packaged integrated circuits for longevity

Procurement Notes

Verify the specific manufacturing date code and lot traceability upon procurement, as Rochester Electronics sources refurbished or surplus original manufacturer dies. Confirm that the ceramic package integrity remains intact, particularly the glass seal, to ensure hermeticity standards are met for your application environment. Request detailed test reports or screening data if required by your quality assurance protocols to validate performance against original specifications.

Selection Notes

Select this component when a high-speed OR gate is needed in a hermetically sealed ceramic package for extreme temperature stability. It is appropriate for designs replacing legacy TTL or early CMOS families where long-term availability and ruggedness are critical. Ensure the system voltage aligns with the 4.5 V to 5.5 V range and that the 14-pin DIP footprint matches the PCB layout constraints.

Part Context

This part belongs to the 54ACT series, which represents advanced CMOS logic compatible with TTL outputs but offering superior speed and lower power than standard LS or HC families. The 'Q' suffix typically denotes a qualified version, often associated with military or aerospace specifications. Rochester Electronics specializes in sustaining these legacy parts, providing lifecycle support for components no longer actively produced by original semiconductor manufacturers.

Replacement Considerations

Direct pin-compatible replacements include other 54ACT32 variants in ceramic DIP packages from original manufacturers like Motorola or Fairchild, provided they meet the same temperature and voltage ratings. Verify that any substitute maintains the CHMOS III process characteristics for equivalent switching speeds and noise immunity.
