5 / 14 page ST2378E 5/14 1) Typical values are referred to TA=25°C 2) Power Supply Range: VL,VCC 1.8V±5%, 2.5±0.2V, 3.3±0.3V, 5.0±0.5V 5) For normal operation, ensure VL<(VCC + 0.3V). During power-up, VL >(VCC + 0.3V) will not damage the device AC ELECTRICAL CHARACTERISTICS 1) Typical values are referred to TA=25°C 2) Power Supply Range: VL,VCC 1.8V±5%, 2.5±0.2V, 3.3±0.3V, 5.0±0.5V. 3) Rise Time:10% to 90%, Fall Time 90% to 10% 4) tpd: 50% to 50% 5) For normal operation, ensure VL<(VCC + 0.3V). During power-up, VL >(VCC + 0.3V) will not damage the device 6) Skew is defined as the absolute value of the difference between the actual propagation delay for any two outputs of the same device switching in the same direction, either HIGH or LOW (tOSLH =| tPLHm -tPLHn|, tOSHL =|tPHLm -tPHLn| 7) Each translator equally loaded; parameter guaranteed by design 8) For VCC =VL =1.8V, tr =tf ≤ 4ns ITS-VCC High Impedance Mode Quiescent Supply Current VCC 1.8to5.5 VL to 5.5 OE= GND 11 µA ITS-VL High Impedance Mode Quiescent Supply Current VL 1.8to5.5 VL to 5.5 OE= GND I/OVL =GND or VL I/OVCC =GND or VCC 11 µA Symbol Parameter Test Condition Value Unit VL(*) (V) VCC(*) (V) TA =25°C -40to 85°C Min.
