ILX3483
INTERFACE TRANSCEIVER OF THE SERIAL DATA
OF THE STANDARD RS -485
(compatible to MAX3483 (MAXIM USA)
ILX3483N is interface transceiver of serial data. ILX3483N is purposed for
application in low power telecom systems, that correspond to RS – 485, RS – 422
standards, level translators, transceiver units & E-field sensitive automation systems of
industrial devices.
Functions and structure:
• Microcircuit contains 1 transmitter and 1 receivers of the serial data of the standard
RS-485.
• The microcircuit supply voltage range is from 3.0 to 3.6 V.
• The microcircuits is available in 8-pin DIP-package (MS-001BA).

Propagation delays difference for ON –OFF switching tSKD, ns is calculated by
formula
tSKD = ⎢ tPLH – tPHL ⎢ ,

tPLH, tPHL,– propagation delays of signal from receiver inputs A or B to RO output for
ON – OFF switching, ns
On signal changing on А input, constant voltage 1,5V applied to input B .
On signal changing on B input, constant voltage 1,5V applied to input A .
