LOW-VOLTAGE 16-BIT BUS SWITCH
DC ELECTRICAL CHARACTERISTICS OVER OPERATING RANGE
Following Conditions Apply Unless Otherwise Specified:
Operating Condition: TA = –40°C to +85°C
NOTES:
1. Typical values are at 3.3V, +25°C ambient.
2. The increase in supply current is attributable to each input that is at the specified voltage level rather than VCC or GND.
3. This is measured by the voltage drop between the A and B terminals at the indicated current through the switch.

Propagation Delay — 0.15 — 0.25 ns

tEN Output Enable Time 1 5 1 4.5 ns
OE to A or B
tDIS Output Disable time 1 5.5 1 5 ns
OE to A or B
NOTE:
1. 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 impededance).
