9 / 15 page SN74CBTU4411 11BIT 1OF4 FET MULTIPLEXER/DEMULTIPLEXER 1.8V DDRII SWITCH WITH CHARGE PUMP AND PRECHARGED OUTPUTS SCDS192 − APRIL 2005 9 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 PARAMETER MEASUREMENT INFORMATION (Enable and Disable Times) VOH VOL CL (see Note A) TEST CIRCUIT T1† VDD GND RL RL Output Waveform 1 (VO) T1† at 2 y VDD (see Note C) Output Waveform 2 (VO) T1† at GND (see Note C) tPZL tPZH tPLZ tPHZ VOL + V∆ VOH − V∆ VOL VREF+0.25 V VOH VOLTAGE WAVEFORMS ENABLE AND DISABLE TIMES NOTES: A. CL includes probe and jig capacitance. B. Output control applies to select (S0, S1) inputs. C. 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. D. All input pulses are supplied by generators having the following characteristics: ZOS = 50 Ω,rising and falling edge rate is 1 V/ns. E. The outputs are measured one at a time, with one transition per measurement. F. tPLZ and tPHZ are the same as tdis. G. tPZL and tPZH are the same as ten.
