Dual bus switch
10. Static characteristics
[1]
All typical values are at VCC = 5 V, Tamb = 25 °C.
[2]
This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.
[3]
Measured by the voltage drop between the nA and the nB terminals at the indicated current through the switch. ON resistance is
determined by the lowest voltage of the two (nA, nB) terminals.
11. Dynamic characteristics
[1]
The propagation delay is the calculated RC time constant of the typical ON resistance of the switch and the specified load capacitance,
when driven by an ideal voltage source (zero output impedance).
[2]
tpd is the same as tPLH and tPHL.
ten is the same as tPZL and tPZH.
tdis is the same as tPLZ and tPHZ.
