NOTES:
1. All typical values are at VCC = 5 V, TA = 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-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).
