ADM4168E data sheet rev. 0 | page 10 of 12 theory of operation the ADM4168E is a dual rs - 422 transceiver that operates from a single 5 v 10% power supply. the ADM4168E is intended for balanced data transmission and complies with tia/eia - 422- b and itu - t recommendation v.11. each device contains two differential line drivers and two differential line receivers and is suitable for full - duplex data transmission. the receiver s contain a fail - safe feature that results in a logic high output state if the inputs are unconnected (floating). the ADM4168E features a low propagation delay, ensuring maximum baud rate operatio n. the balanced driver ensure s distortion - free transmission. another important specification is a measure of the skew between the complementary outputs. low skew enhances the noise immunity of the system and decreases the amount of electromagnetic interf erence (emi). truth tables table 6 . abbreviations in truth tables letter description h high level i indeterminate l low level x irrelevant z high impedance (off ) table 7 . transmitting (each driver) inpu ts outputs de di z y h h l h h l h l l x z z table 8 . receiving (each receiver) inputs output a ? b ro +0.2 v h ?0.2 v l ?0.2 v < a ? b < +0.2 v i inputs open h www.datasheet.net/ datasheet pdf - http://www..co.kr/
