Logic Input-Output Electrical Characteristics (Continued)

Note 4: Besides checking the cutoff frequency (fc) and the stopband attenuation at 2 fc, two additional frequencies are used to check the magnitude response of the

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− = 0V and will scale accordingly for ±5V and ±2.5V supplies (except for the TTL input logic lev-

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

Ω resistor.

Note 13: When the input voltage (VIN) at any pin exceeds the power supply rails (VIN < V

− or V

IN > V

+) the absolute value of current at that pin should be limited

to 5 mA or less. The 20 mA package input current limits the number of pins that can exceed the power supply boundaries witha5mA current limit to four.

Note 14: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the ambient temperature, TA. The maximum

allowable power dissipation at any temperature is PD = (TJMAX −TA)/θJA or the number given in the Absolute Maximum Ratings, whichever is lower. For this device,

TJMAX = 125˚C, and the typical junction-to-ambient thermal resistance is 78˚C/W. For the MF6CJ this number decreases to 62˚C/W. For MF6CWM, θJA = 78˚C/W.
