4.7 Electrical Characteristics: Receiver

over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted)
PARAMETER TEST CONDITIONS MIN TYP(1) MAX UNIT
VIT+ Positive-going input threshold voltage VO = 2.7V IO = –0.4mA 0.2 V
VIT- Negative-going input threshold voltage VO = 0.5V IO = 8mA –0.2(2) V
Vhys| Hysteresis voltage (VIT+ – VIT– ) 50 mV
VOH High-level output voltage VID = 200mV IOH = -400µA See Figure 5-2 2.7 V
VOL Low-level output voltage VID = -200mV IOL = 8mA See Figure 5-2 0.45 V
II Line input current Other input at 0V See (3) VI = 12V 1 mA
VI = –7V –0.8 mA
rI Input resistance 12 kΩ
IOS Short-circuit output current –15 –85 mA
IOS Supply current (total package) No load 57 70 mA
(1) All typical values are at VCC = 5V and TA = 25°C.
(2) The algebraic convention, where the less positive (more negative) limit is designated minimum, is used in this data sheet for common-mode input voltage and threshold voltage levels only.
(3) See TIA/EIA-422-B for exact conditions.
