VTH Differential input high threshold VCM = 1.2 V, RIN+, RIN– pin(2) 20 100 mV
VTL Differential input low threshold –100 –20 mV
VCMR Common mode voltage range VID = 200 mV peak to peak, RIN+, RIN– pin(3) 0.1 2.3 V
IIN Input current VCC = 3.6 V or 0 V,
RIN+, RIN– pin		 VIN = 2.8 V –10 ±1 10 µA
VIN = 0 V –10 ±1 10 µA
VCC = 0 V, VIN = 3.6 V, RIN+, RIN– pin –20 20 µA

IOH = –0.4 mA, input shorted, ROUT pin 2.7 3 V
VOL Output low voltage IOL = 2 mA, VID = –200 mV, ROUT pin 0.1 0.25 V
IOS Output short-circuit current Enabled, VOUT = 0 V, ROUT pin(4) –15 –48 –120 mA
IOZ Output TRI-STATE current Disabled, VOUT = 0 V or VCC –10 ±1 10 µA
VIH Input high voltage EN, EN* pins 2 VCC V
VIL Input low voltage EN, EN* pins GND 0.8 V
II Input current VIN = 0 V or VCC, other input = VCC or GND, EN, EN* pins –10 ±1 10 µA
VCL Input clamp voltage ICL = –18 mA, EN, EN* pins –1.5 –0.8 V
ICC No load supply current EN, EN* = VCC or GND, inputs open, VCC pin 10 15 mA

ICCZ No load supply current Receivers disabled, EN = GND, EN* = VCC, inputs open, VCC pin 3 5 mA
(1) Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground unless otherwise specified.
(2) VCC is always higher than RIN+ and RIN– voltage. RIN– and RIN+ are allowed to have a voltage range –0.2 V to VCC – VID / 2. However, to be compliant with AC specifications, the common voltage range is 0.1 V to 2.3 V
(3) The VCMR range is reduced for larger VID. Example: if VID = 400 mV, the VCMR is 0.2 V to 2.2 V. The fail-safe condition with inputs shorted is valid over a common mode range of 0 V to 2.3 V. A VID up to VCC – 0 V may be applied to the RIN+/ RIN– inputs with the common mode voltage set to VCC / 2. Propagation delay and differential pulse skew decrease when VID is increased from 200 mV to 400 mV. Skew specifications apply for 200 mV ≤ VID ≤ 800 mV over the common mode range.
(4) Output short-circuit current (IOS) is specified as magnitude only, minus sign indicates direction only. Only one output must be shorted at a time, do not exceed maximum junction temperature specification.

(3) tSKD1 is the magnitude difference in differential propagation delay time between the positive going edge and the negative going edge of the same channel
(4) tSKD2, channel-to-channel skew, is defined as the difference between the propagation delay of one channel and that of the others on the same chip with any event on the inputs.
(5) tSKD3, part-to-part skew, is the differential channel-to-channel skew of any event between devices. This specification applies to devices at the same VCC, and within 5°C of each other within the operating temperature range.
(6) tSKD4, part-to-part skew, is the differential channel-to-channel skew of any event between devices. This specification applies to devices over recommended operating temperature and voltage ranges, and across process distribution. tSKD4 is defined as |Maximum – Minimum| differential propagation delay.
