Logic Input-Output Electrical Characteristics
Note 4: Besides checking the cutoff frequency (f
filter. The magnitudes are referenced to a DC gain of 0.0 dB.
Note 5: For simplicity all the logic levels have been referenced to V
els).
Note 6: The short circuit source current is measured by forcing the output that is being tested to its maximum positive voltage swing and then shorting that output
to the negative supply. The short circuit sink current is measured by forcing the output that is being tested to its maximum negative voltage swing and then shorting
that output to the positive supply. These are the worst-case conditions.
Note 7: The MF6 is operating with symmetrical split supplies and L.Sh is tied to ground.
Note 8: Typicals are at 25˚C and represent most likely parametric norm.
Note 9: Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 10: Design limits are guaranteed, but not 100% tested. These limits are not used to calculate outgoing quality levels.
Note 11: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating
the device beyond its specified conditions.
Note 12: Human body model, 100 pF discharged through a 1.5k
Note 13: When the input voltage (V
to 5 mA or less. The 20 mA package input current limits the number of pins that can exceed the power supply boundaries with a 5 mA current limit to four.
Note 14: The maximum power dissipation must be derated at elevated temperatures and is dictated by T
allowable power dissipation at any temperature is P
