5.2.5 Electrical Characteristics

over recommended operating conditions
PARAMETER TEST CONDITIONS MIN TYP(1) MAX UNIT
VIK Input clamp voltage II = –18 mA –1.5 –0.77 V
VO Open-circuit output voltage Y or Z, No load 0 VCC V
|VOD(SS)| Steady-state differential output
voltage magnitude(2) 		No load (open circuit) 3 VCC V
RL = 54 Ω, See Figure 7 0.8 1.6 2.5
With common-mode loading, See Figure 8 0.8 1.6 2.5
ΔVOD(SS) Change in steady-state differential output voltage between logic states See Figure 7 –0.1 0.1 V
VOC(SS) Steady-state common-mode output voltage See Figure 9 2 2.4 2.8 V
ΔVOC(SS) Change in steady-state common-mode output voltage between logic states See Figure 9 –0.04 0.04 V
II Input current A, G, G –70 70 μA
IOS Short-circuit output current VTEST = –7 V to 12 V,
See Figure 13 		VI = 0 V –200 200 mA
VI = VCC
IOZ High-impedance-state output current EN at 0 V –50 50 μA
IO(OFF) Output current with power off VCC = 0 V –10 10 μA
ICC Supply current VI = 0 V or VCC,
No load		 All drivers enabled 25 mA
All drivers disabled 1.5
(1) All typical values are at VCC = 5 V and 25°C.
(2) The minimum VOD may not fully comply with TIA/EIA-485-A at operating temperatures below 0°C. System designers should take the possibility of lower output signal into account in determining the maximum signal transmission distance.
