Typical Applications and Termination Methods

(1) Analog circuit	r: Impedance of signal source Rin: Input adjustment resistance Zo: Characteristics impedance of internal Elements (=Output impedance) Ro: Internal adjustment resistance (=Zo) 2(r+Rin)=Zo=R
(2) ECL (-2V termination line used)
(3) PECL
(4) LVPECL
(5) TTL (FAST) For VDS**10 Type IOH is approx. 45mA, IOL is approx. 15mA
(6) TTL (FAST) For VDS**20 Type
(7) CMOS,LVCMOS Printable Version - High Resolution PDF
