SEMICONDUCTOR TECHNICAL DATA  
The MC145442B and MC145443B silicon–gate CMOS single–chip low–  
speed modems contain a complete frequency shift keying (FSK) modulator,  
demodulator, and filter. These devices are compatible with CCITT V.21  
(MC145442B) and Bell 103 (MC145443B) specifications. Both devices provide  
full–duplex or half–duplex 300–baud data communication over a pair of  
telephone lines. They also include a carrier detect circuit for the demodulator  
section and a duplexer circuit for direct operation on a telephone line through a  
simple transformer.
