Frequently Asked Questions
How many inverter gates does CD54HCT04F3A contain and what is each gate's load capacitance limit?
The CD54HCT04F3A contains 6 independent single-input inverter gates, each rated for 50 pF of load capacitance. This allows driving standard PCB traces and small capacitive loads such as gate inputs of companion logic devices without exceeding timing specifications or degrading signal integrity.
What makes the HCT family of CD54HCT04F3A suitable for TTL-to-CMOS interface designs?
The HCT family uses TTL-compatible input voltage thresholds — accepting logic-high inputs starting from 2 V — while delivering standard CMOS output swings close to VCC. This makes CD54HCT04F3A ideal for bridging 5 V TTL outputs to CMOS logic systems, requiring no additional pull-up resistors or voltage translators for reliable inversion.
Why does CD54HCT04F3A use a ceramic DIP package rather than a plastic package?
The 14-pin ceramic DIP (CDIP) package provides hermetic sealing that protects the die from moisture, contamination, and corrosive gases, making it suitable for military, aerospace, and industrial applications where plastic packages fail over decades. Its 15-year YTEOL rating reflects the extended service life expected in defence electronics and space-grade systems.
When would a designer select CD54HCT04F3A instead of a plastic-package 74HCT04 inverter?
A designer would choose CD54HCT04F3A over a plastic 74HCT04 when the end product must meet MIL-SPEC or IPC Class 3 reliability standards — for example, avionics, downhole oil-field tools, or satellite equipment — where ceramic hermetic packaging provides greater resistance to thermal shock across -55°C to +125°C than plastic SOIC or TSSOP packages.
