SN54HC682, SN74HC682 8-BIT MAGNITUDE COMPARATORS SCLS018D – MARCH 1984 – REVISED MARCH 2003 5 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 PARAMETER MEASUREMENT INFORMATION VOLTAGE WAVEFORM INPUT RISE AND FALL TIMES 50% 50% 10% 10% 90% 90% VCC 0 V tr tf Input VOLTAGE WAVEFORMS PROPAGATION DELAY AND OUTPUT TRANSITION TIMES 50% 50% 50% 10% 10% 90% 90% VCC VOH VOL 0 V tr tf Input In-Phase Output 50% tPLH tPHL 50% 50% 10% 10% 90% 90% VOH VOL tr tf tPHL tPLH Out-of-Phase Output Test Point From Output Under Test CL = 50 pF (see Note A) LOAD CIRCUIT NOTES: A. CL includes probe and test-fixture capacitance. B. Phase relationships between waveforms were chosen arbitrarily. All input pulses are supplied by generators having the following characteristics: PRR ≤ 1 MHz, ZO = 50 Ω, tr = 6 ns, tf = 6 ns. C. The outputs are measured one at a time with one input transition per measurement. D. tPLH and tPHL are the same as tpd. Figure 1. Load Circuit and Voltage Waveforms |
