Note 2: Testing done at VCC = 5V and VON/OFF = 3V, unless otherwise specified. Note 3: Supply current is measured as the average over several charge pump burst cycles. C+ = 1.0 µF, C– = 0.1µF, C1 = C2 = 0.2µF. All outputs are open, with all driver inputs tied high. Note 4: Measurements in shutdown are performed with VON/OFF ≤ 0.1V. Supply current measurements using driver disable are performed with VDRIVER DISABLE ≥ 3V. Note 5: For driver delay measurements, RL = 3k and CL = 51pF. Trigger points are set between the driver’s input logic threshold and the output transition to the zero crossing (tHL = 1.4V to 0V and tLH = 1.4V to 0V). Note 6: For receiver delay measurements, CL = 51pF. Trigger points are set between the receiver’s input logic threshold and the output transition to standard TTL/CMOS logic threshold (tHL = 1.3V to 2.4V and tLH = 1.7V to 0.8V). Note 7: Data rate operation guaranteed by slew rate, short-circuit current and propagation delay tests. The q denotes specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. (Note 2) |
