It contains both receive and transmit circuitry in a 16-pin dual-in-line plastic package. The receiver is designed for short line applications having a cable loss up to 10dB measured at the half bit rate. The transmitter has open collector line driver outputs that are capable of handling up to 40mA. When used in conjunction with either XRT6165 or XRT6166, the chip set provides a 64Kbps codirectional interface as specified in CCITT G.703.
