R8071A

The R8071A is designed as ISDN link layer controller with typical applications of primary rate interfaces and basic rate D-channel controller.

The R8071A has many features. The first one is ISDN implementation, solidly based on T1 and CEPT primary rate carrier with designed-in compatibity with ISDN, is the key to world-wide networking. The second one is single chip CMOS monolithic device simplifies ISDN/DMI implementation. The third one is provides up to 32 full duplex channels with HDLC/SDLC protocol formatting. The fourth one is supports all four DMI B channel data options. The fifth one is support bith DMI D channel signallig options. The sixth one is compatible with 1.544 Mbps T1 SF and ESF as well as 2.048 Mbps CEPT PCM 30 carrier format. The seventh one is supports both flag stuffing (1.462, DMI mode 2) and RA2 intermediate rate adaption. The eighth one is compatible with HDLC, SNA SDLC, X.25, X.75, LAPB and LAPD protocols. The ninth one is on-board buffer memory management function. The tenth one is operate from a single +5V Vdc supply. And so on. That are all the main features.

Some absolute maximum ratings of R8071A have been concluded into several points as follow. The first one is about its supply voltage which would be from -0.3V to 7.0V. The second one is about its operating temperature range which would be from 0°C to +70°C. The third one is about its storage temperature range which would be from -55°C to +150°C. It should be noted that stresses above those listed may cause permanent damage to the device. This a stress rating only and functional operation of the device at these or any other conditions above those indicated in the other sections is not implied. And so on.
