PARAMETER MEASUREMENT INFORMATION FOR B TO A PORT

VCCA =2.7V TO 3.6V and VCCB = 5V ± 0.5V

Load Circuit

Voltage Waveforms

Propagation Delay Times

Voltage Waveforms

Enable and Disable Times

Notes:

A. CL includes probe and jig capacitance.

B. 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 impulses are supplied by generators having the following characteristics: PRR ≤ 10 MHz, ZO = 50Ω, tR ≤ 2.5ns, tF ≤ 2.5ns.

• The outputs are measured one at a time with one transition per measurement.
