APPLICATION INFORMATION
using the SN75112 as a CCITT recommended V.35 line driver
The SN75112 dual line driver, the SN75107A dual line receiver, and some external resistors can be used to
implement the data interchange circuit of CCITT recommendation V.35 (1976) modem specification. The circuit
of one channel is shown in Figure 1 and meets the requirement of the interface as specified by Appendix 11 of
CCITT V.35 and summarized in Table 1 (V.35 has been replaced by ITU V.11).
