The SN75146D can support data rates up to 10 Mbps, making it suitable for high-speed applications such as industrial control systems and medical devices.
The SN75146D has a high common-mode rejection ratio (CMRR) of 80 dB, which helps to reject common-mode noise and EMI. Additionally, it has a built-in electromagnetic interference (EMI) filter to further reduce the effects of EMI.
The maximum cable length that can be used with the SN75146D depends on the data rate and the type of cable used. As a general rule, the maximum cable length is approximately 100 meters at 10 Mbps, but this can be extended to several hundred meters at lower data rates.
Yes, the SN75146D can be used in half-duplex mode by connecting the transmitter output to the receiver input through a directional coupler or a switch. This allows the device to transmit and receive data on the same wire, but not simultaneously.
The power consumption of the SN75146D depends on the operating mode and the supply voltage. Typically, the device consumes around 20 mA of current from a 5V supply voltage, but this can increase to around 50 mA at higher data rates or with heavier loads.
