MC145422DW

The MC145422DW is one member of the MC145422 family which designed as one kind of high-speed data transceivers that provide 80 kbps fullduplex data communication over 26 AWG and larger twistedpair cable up to two kilometers in distance.It can be used in remote data acquisition and control systems, digital subscriber voice/data telephone systems.And it consists of the MC145422 Master UDLT for use at the telephone switch linecard and the MC145426 Slave UDLT for use at the remote digital telset and/or data terminal.

Features of the MC145422DW are:(1)provides full-duplex synchronous 64 kpbs voice/data channel and two 8 kbps signaling data channels over one 26 AWG wire pair up to two kilometers;(2)compatible with existing and evolving telephone switch architectures and call signaling schemes;(3)automatic detection threshold adjustment for optimum performance over varying signal attenuations;(4)protocol independent;(5)single 5 V power supply;(6)22-pin PDIP, 24-Pin SOG packages;(7)application notes AN943, AN949, AN968, AN946, and AN948.

The absolute maximum ratings of the MC145422DW can be summarized as:(1)DC supply voltage:-0.5 to 9.0 V;(2)voltage. any pin to Vss:-0.5 to Vdd+0.5 V;(3)DC current,any pin:+10 mA;(4)operating temperature:-40 to +85;(5)storage temperature:-85 to +150.If you want to know more information such as the electrical characteristics about the MC145422DW,please download the datasheet in www.seekic.com or www.chinaicmart.com .
