OCTAL LINE RECEIVER
ADVANCE DATA
OCTAL LINE RECEIVERFOR:
- EIA STD RS232D RS423A RS422A
- CCIT V.10 V.11 V.28 X.26
DESCRIPTION
L6180/1 is an octal line receiver in a plastic DIP or PLCC designed to meet a wide range of digital communications requirements as outlined in the EIA standards RS232A without additional compo­nents, as well as the low speed applications of RS422A.
The receiver meets the CCIT recommendations V.10, V.11, X.26and V.28 low speed applications (below100KBS). A low pass filter on the input starts to roll off at a frequencyof 100KHz.
This is advancedinformation on a new product now in developmentor undergoing evaluation. Details are subject to change without notice.

INPUTBALANCE MEASUREMENT
The balance of the receiver input voltage-current characteristics and bias voltages shall be such that the receiverwill remainin theintendedbinary state when a differential voltage Vi of 400mV is appliedthrough 500±1% to each input terminal, as shown above, and Vcm is varied between -7 and +7V.
When the polarity of Vi is reversed, the opposite binary state shall be maintained under the same conditions. Maintain input balance with input B commonwith another receiver.
The voltage input (V
IN) rejection is checked at the
center point between the High Operating Thresh­old (V
th2) and theLow OperatingThreshold(Vth1)
