PARAMETER TEST CONDITIONS MIN TYP MAX UNIT IOH = –4 mA; see Figure 1 VCCx (1) – 0.5 3 VOH High-level output voltage V IOH = –20 μA; see Figure 1 VCCx (1) – 0.1 3.3 IOL = 4 mA; see Figure 1 0.2 0.4 VOL Low-level output voltage V IOL = 20 μA; see Figure 1 0 0.1 VI(HYS) Input threshold voltage hysteresis 425 mV IIH High-level input current VIH = VCC at INx or ENx 10 μA IIL Low-level input current VIL = 0 V at INx or ENx –10 Common-mode transient CMTI VI = VCC or 0 V; see Figure 4 25 50 kV/ μs immunity (1) VCCx is the supply voltage, VCC1 or VCC2, for the output channel that is being measured. SWITCHING CHARACTERISTICS VCC1 and VCC2 at 3.3 V ± 10% (over recommended operating conditions unless otherwise noted.) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT tPLH, tPHL Propagation delay time 15 23 45 See Figure 1 PWD(1) Pulse width distortion |tPHL – tPLH| 3 Same-direction Channels 2 ns tsk(o) (2) Channel-to-channel output skew time Opposite-direction 4 Channels tsk(pp) (3) Part-to-part skew time 19 tr Output signal rise time 2.5 See Figure 1 ns tf Output signal fall time 2.5 Disable propagation delay, from high/low to tPHZ, tPLZ 6.5 15 high-impedance output See Figure 2 ns Enable propagation delay, from high- tPZH, tPZL 6.5 15 impedance to high/low output Fail-safe output delay time from input data or tfs See Figure 3 8 μs power loss tGR Input glitch rejection time 12.5 ns (1) Also known as pulse skew (2) tsk(o) is the skew between outputs of a single device with all driving inputs connected together and the outputs switching in the same direction while driving identical loads. (3) tsk(pp) is the magnitude of the difference in propagation delay times between any terminals of different devices switching in the same direction while operating at identical supply voltages, temperature, input signals and loads. 6 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: ISO7131CC ISO7140CC ISO7140FCC ISO7141CC ISO7141FCC |
