Octal bus switch with quad output enables
9.
Static characteristics
[1]
All typical values are at VCC =5V; Tamb =25 °C.
[2]
This is the increase in supply current for each input that is at the specied 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.
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-state
resistance of the switch and a load capacitance of 50 pF, when driven by an ideal voltage source (zero output impedance).
[2]
Output enable time to HIGH and LOW level.
[3]
Output disable time from HIGH and LOW level.
