In applications with fast edge rates, multiple outputs switching, and operating at high frequencies, the output may have little or no level-shifting

effect.

NOTE 3: All unused control inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application report,

† Typical values are at VCC = 5 V, TA = 25°C.

‡ This is the increase in supply current for each input that is at the specified TTL voltage level, rather than VCC or GND.

§ Measured by the voltage drop between the A and 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.

¶ The propagation delay is the calculated RC time constant of the typical on-state resistance of the switch and the specified load capacitance, when

driven by an ideal voltage source (zero output impedance).
