Dual 1-of-4 FET multiplexer/demultiplexer

9.

Static characteristics

[1]

All typical values are measured at VCC =5V; 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 A and the B terminals at the indicated current through the switch. The lowest voltage of the

two (A or B) terminals determines the ON resistance.

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.
