Frequently Asked Questions
What is the operating temperature range of the CD54HC125F3A?
The CD54HC125F3A operates over a full military-grade temperature range of -55°C to +125°C, making it suitable for harsh environment applications in aerospace and defense systems where standard commercial-grade components would fail.
How many buffers does the CD54HC125F3A contain and how are they controlled?
The CD54HC125F3A contains four independent three-state buffers. Each buffer is individually controlled by an active-low output enable (OE) pin, allowing flexible bus management. When any OE pin is high, the corresponding buffer output enters a high-impedance state.
What package does the CD54HC125F3A use and why is it significant?
The CD54HC125F3A uses a 14-pin ceramic dual in-line package (CDIP), which provides superior hermeticity and reliability compared to plastic packages. This ceramic construction meets MIL-spec requirements and is preferred for long-life, high-reliability applications in military and space environments.
What is the load capacitance specification for the CD54HC125F3A?
The CD54HC125F3A is characterized with a load capacitance (CL) of 50 pF per output, which is the standard test condition used to specify propagation delay and output drive capability for this high-speed CMOS logic device.
What are common replacements or alternatives for the CD54HC125F3A?
Common alternatives include the SN74HC125 series in plastic packages for commercial use, or the CD74HC125E for a ceramic DIP variant. For drop-in military replacements with similar performance, look for 74HC125 devices from other vendors rated to -55°C to +125°C with compatible pinouts.
