Quad FET bus switch
[1] All typical values are measured at VCC=5V; T
amb=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 A and the B terminals at the indicated current through the switch. ON resistance is
determined by the lowest voltage of the two (A or B) terminals.
10. Dynamic characteristics
[1] This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical ON
resistance of the switch and a load capacitance, when driven by an ideal voltage source (zero output impedance).
[2] tPLH and tPHL are the same as tpd;
tPZL and tPZH are the same as ten;
tPLZ and tPHZ are the same as tdis.

tpd propagation delay nA to nB or nB to nA; see Figure 5 [1][2] - 0.25 ns
ten enable time OE to nA or nB; see Figure6 [2] 1.6 4.5 ns
tdis disable time OE to nA or nB; see Figure 6 [2] 1.0 5.4 ns
Measurement points are given inTable 8.
VOL and VOH are typical voltage output levels that occur with the output load.
