This device is offered in a plastic dual in-line (PDIP) or in a surface mount package (SOIC). The maximum bit rate of the chip is 8.448Mbps, and the signal level to the receiver can be attenuated by -10dB cable loss at one-half the bit rate. At nominal supply voltage operation, the typical current consumption is 40mA.
