Frequently Asked Questions
Q: Is the ST7540 suitable for low-frequency narrowband power line communication?
A: No, the ST7540 is a half-duplex transceiver for FSK protocol, designed for 3kHz to 500kHz band; but its Part Status is Obsolete, so it is not recommended for new designs.
Q: What is the operating supply voltage range for this transceiver?
A: The ST7540 requires a supply voltage between 5V and 9V, making it compatible with standard 5V logic and wide-voltage analog systems.
Q: Can the ST7540 be used in full-duplex communication?
A: No, it supports only half-duplex operation, meaning the 1 driver and 1 receiver cannot transmit and receive simultaneously.
Q: What is the mounting type and recommended package for the ST7540?
A: It is surface mount. The supplier device package is 28-HTSSOP with an exposed pad, which improves thermal dissipation.
Q: What are the key design-in issues when using this Obsolete part?
A: The part is marked Obsolete; ensure stock availability and consider potential long-term supply constraints before integrating into production.
