Frequently Asked Questions
What is the operating temperature range of the SN54HC03J?
The SN54HC03J is rated for military temperature range from -55°C to 125°C, making it suitable for extreme environment applications in aerospace, defense, and industrial systems where commercial-grade ICs would fail.
What supply voltage does the SN54HC03J support?
The SN54HC03J operates over a wide supply voltage range of 2 V to 6 V, allowing compatibility with both 3.3 V and 5 V logic systems and enabling flexibility in mixed-voltage board designs.
Why does the SN54HC03J use open-drain outputs instead of push-pull?
Open-drain outputs allow multiple devices to share a common bus line in wired-AND configurations. This enables logic operations without bus contention and supports driving loads such as LEDs, relays, or level-shifted signals with an external pull-up resistor.
What package does the SN54HC03J come in and how many gates does it contain?
The SN54HC03J is housed in a 14-pin ceramic dual in-line package (CDIP), and it contains four independent 2-input NAND gates. The ceramic package provides superior moisture resistance and reliability compared to plastic packages for military applications.
What is the maximum output sink current (Iol) of the SN54HC03J?
The maximum output sink current (Iol) is 5.2 mA at the rated supply voltage. This parameter is critical when designing pull-up resistor networks or driving low-current loads directly from the open-drain outputs.
