V.21/V.23 Telemeter Modem
**The MC145745 is a selectable modem chip compatible with ITU V.21 (300
baud full duplex asynchronous) and V.23 mode 2 (1200 baud half duplex asynchronous). The built–in differential line driver has the capability of driving 0 dBm into a 600 Ω load with a 5 V single power supply. This device also includes a DTMF generator, DTMF receiver, call–progress tone detector, answer tone generator, and a receive timing control circuit.**
A low consumption device, the MC145745 integrates various functions in a small package. This modem IC is best suited for telemeter and other applications of this type.
