5.6 Electrical Characteristics - Reciever

over operating free-air temperature range (unless otherwise noted)
PARAMETER TEST CONDITIONS MIN TYP(1) MAX UNIT
VIT+ Positive-going input threshold voltage VO = 2.7 V IO = -0.4 mA 0.2 V
VIT- Negative-going input threshold voltage VO = 0.5 V IO = 8 mA -0.2(3) V
Vhys Hysteresis voltage (VIT+ − VIT−) (see Figure 4) 50 mV
VIK Enable-input clamp voltage II = -18 mA -1.5 V
VOH High-level output voltage VID = 200 mV
IOH = -400 µA		 See Fig 6 2.7 V
VOL Low-level output voltage VID = 200 mV
IOL = 8 mA		 See Fig 6 0.45 V
IOZ High-impedance-state output current VO = 0.4 V to 2.4 V ±20 µA
II Line input current Other input = 0 V(5) VI = 12 V 1 mA
VI = -7 -0.8 mA
IIH High-level enable-input current VIH = 2.7 V -100 µA
IIL Low-level enable-input current VIL = 0.4 V -100 µA
rI Input resistance 12 kΩ
ICC Supply current VI = 0 or VCC,
No Load		 Receiver disabled and driver enabled 3.9 mA
Receiver and driver disabled 0.25 mA
(1) All typical values are at VCC = 5 V, TA = 25°C.
(3) The algebraic convention, in which 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.
(5) This applies for both power on and off; refer to ANSI Standard RS-485 for exact conditions.
