2.5V 10-Bit Flip-Flop
w/Dual and 3-State Outputs
6
PS8696E
06/09/06
PARAMETER MEASUREMENT INFORMATION
VCC = 1.2V and 1.5V ± 0.1V
Load Circuit
Voltage Waveforms Propagation Delay Times
Voltage Waveforms Enable and Disable Times
Voltage Waveforms Pulse Duration
Notes:
1. CL includes probe and jig capacitance.
2. 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 ≤ 2.0ns, tF ≤ 2.0ns.
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
