RS-485 bus is a half-duplex communication bus, so MCU is usually required to control the receiving and sending status of RS-485 transceiver. In order to save MCU I/O resources, RS-485 automatic receiv
A novice asks for help:I recently need to use a transformer to design a microwave device. As a part of the microwave network, it is used for high frequency (more than 300-400 MHz, preferably G) and we
[size=5][color=rgb(62, 62, 62)]1. When the TTL circuit drives the COMS circuit, if the high level output by the TTL circuit is lower than the lowest high level of the COMS circuit (usually 3.5V), then
