24-Bit, 1.8V to 3.3V
BiDirectional Level Shifting Transceiver
Parameter Measurement Information - B to A Direction
VCCB = 3.3V±0.3V and VCCA = 1.8V ±0.10V
Figure 1. Load Circuit and Voltage Waveforms
Notes:
A. CL includes probe and jig capacitance.
Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
All input pulses are supplied by generators having the following characteristics: PRR
≤ 10Mz, ZO = 50-ohm,
tR
≤ 2.5ns, tF ≤ 2.5ns.
The outputs are measured one at a time with one transition per measurement.
tPLZ and tPHZ are the same as tDIS.
tPZL and tPZH are the same as tEN.
tPLH and tPHL are the same as tPD.
