NOTES:
8. Limits tested 100%
9. 3.3V Min is at 3.6V, Max is at 3V.
10. 5V Min is at 5.5V, Max is at 4.5V.
11. CPD is used to determine the dynamic power consumption per channel.
AC: PD = VCC
2 f
i (CPD + CL)
ACT: PD = VCC
2 f
i (CPD + CL) + VCC ∆ICC where fi = input frequency, CL = output load capacitance, VCC = supply voltage.
NOTES:
12. Input pulses have the following characteristics: PRR
≤ 1MHz, tr = 3ns, SKEW 1ns.
13. R.F. fixture with 700MHz design rules required. IC should be soldered into test board and bypassed with 0.1
µF capacitor. Scope and
probes require 700MHz bandwidth.
