Frequently Asked Questions
What interface standard does the SN75LBC179P support?
The SN75LBC179P supports EIA-485 and ISO 8482 standards. These standards define balanced differential signaling for multi-point bus communication, allowing up to 32 unit loads on a single bus with data rates up to 10 Mbps in typical configurations.
What is the input characteristic of the SN75LBC179P receiver?
The SN75LBC179P receiver features differential Schmitt trigger inputs, which provide hysteresis for superior noise immunity. This makes the device highly reliable in electrically noisy industrial environments, reducing the risk of false triggering from common-mode noise or signal reflections.
What package does the SN75LBC179P come in and where can I buy it?
The SN75LBC179P is available in a DIP-8 (R-PDIP-T8) through-hole package, making it easy to use in prototype and production PCB designs. It is priced from $2.44 and is in stock with worldwide shipping available through FindMyChip.
Can the SN75LBC179P replace other RS-485 transceivers?
The SN75LBC179P is a standard RS-485/RS-422 single-channel driver and receiver pair. It can typically replace compatible 8-pin DIP RS-485 transceivers with similar pin configurations. Always verify supply voltage, data rate, and driver/receiver count specifications before substituting devices in your application.
