NOTES:
1. All typical values are at V
= 5 V, T
= 25
°
C
2. This is the increase in supply current for each input that is at the specified TTL voltage level rather than V
or GND
3. Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. On-state resistance is
determined by the lowest voltage of the two (A or B) terminals.

NOTE:
1. This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical on-state
resistance of the switch and a load capacitance of 50 pF, when driven by an ideal voltage source (zero output impedance).
