HC55185ECMZ96R4854

The HC55185ECMZ96R4854 is designed as one member of he RSLIC-VoIP family which are ringing subscriber line interface circuits (RSLIC). HC55185ECMZ96R4854 supports analog plain old telephone service (POTS) in short and medium loop length, wireless and wireline applications. Ideally suited for remote subscriber units, this family of products offers flexibility to designers with high ringing voltage and low power onsumption system requirements.

HC55185ECMZ96R4854 has many features and some are listed here. (1)Onboard ringing generation. (2)Compatible with existing HC5518x devices. (3)Low standby power consumption (75V, 65mW). (4)Reduced idle channel noise. (5)Programmable transient current limit. (6)Improved off hook software interface. (7)Integrated MTU DC characteristics. (8)Low external component count. (9)Silent polarity reversal. (10)Pulse metering and on hook transmission. (11)Tip open ground start operation. (11)Balanced and unbalanced ringing. And so on.

Some absolute maximum ratings of HC55185ECMZ96R4854 have been concluded into several points as follow. (1)Its maximum supply voltages Vcc would be from -0.5V to +7V and Vcc-Vbh would be 110V and uncommitted switch voltage would be -110V. (2)Its maximum tip/ring negative voltage pulse would be VBH-15V. (3)Its maximum tip/ring positive voltage pulse would be +8V. (4)Its ESD human body model would be 500V. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of HC55185ECMZ96R4854 are concluded as follow. (1)Its VRS input impedance would be min 450Kohms. (2)Its differential ringing gain would be min 78V/V and typ 80V/V and max 82V/V for balanced ringing and would be typ 40V/V for unbalanced ringing. (3)Its ringing voltage total distortion would be max 4.0%. (4)Its 4-wire to 2-wire ringing off isolation would be typ 90dB. (5)Its 2-wire to 4-wire transmit isolation would be typ 80dB. And so on.
