The SN74LS14DBR can operate over a temperature range of 0°C to 70°C.
The SN74LS14DBR is a 5V device, but it can be used in 3.3V systems with proper voltage translation and level shifting.
The SN74LS14DBR can handle clock frequencies up to 30 MHz.
While the SN74LS14DBR is a commercial-grade device, it may not meet the stringent requirements of high-reliability or aerospace applications. Consult with Texas Instruments for more information on their high-reliability or aerospace-grade alternatives.
To ensure EMC, follow proper PCB design and layout guidelines, use shielding and grounding techniques, and consider using electromagnetic interference (EMI) filters or chokes in your design.
