PARAMETER MEASUREMENT INFORMATION

Propagation Delays

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.

C.

All input pulses are supplied by generators having the following characteristics: PRR

≤ 10 MHz, ZO = 50 Ω, for

propagation delays tr/tf = 3 ns, for setup and hold times and pulse width tr/tf = 1.2 ns.

D.

The outputs are measured on at a time, with on transition per measurement.

E.

tPLH and tPHL are the same a tpd.

F.

All parameters and waveforms are no applicable to all devices.
