Note 1:
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 rated operating conditions.
Note 2:
During current limit or thermal limit, the input current will increase if the input to output differential voltage exceeds 8V. For input to output differential voltages
in excess of 8V the input current should be limited to
±
20 mA.
Note 3:
The LM6121 series buffers contain current limit and thermal shutdown to protect against fault conditions.
Note 4:
The thermal resistance
θ
of the device in the N package is measured when soldered directly to a printed circuit board, and the heat-sinking pins (pins 1,
4, 5 and 8) are connected to 2 square inches of 2 oz. copper. When installed in a socket, the thermal resistance
θ
of the N package is 84C/W. The thermal re-
sistance
θ
of the device in the M package is measured when soldered directly to a printed circuit board, and the heat-sinking pins (pins 1, 2, 6, 7, 8, 9, 13, 14) are
connected to 1 square inch of 2 oz. copper.
Note 5:
Limits are guaranteed by testing or correlation.
Note 6:
The input is biased to 2.5V and V
IN
swings V
pp
about this value. The input swing is 2 V
pp
at all temperatures except for the A
V
3 test at 55C where it is
reduced to 1.5 V
pp
.
Note 7:
Slew rate is measured with a
±
11V input pulse and 50
source impedance at 25C. Since voltage gain is typically 0.9 driving a 50
load, the output swing
will be approximately
±
10V. Slew rate is calculated for transitions between
±
5V levels on both rising and falling edges.Ahigh speed measurement is done to minimize
device heating. For slew rate versus junction temperature see typical performance curves. The input pulse amplitude should be reduced to
±
10V for measurements
at temperature extremes. For accurate measurements, the input slew rate should be at least 1700 V/μs.
Note 8:
The test circuit consists of the human body model of 120 pF in series with 1500
.
Note 9:
For specification limits over the full Military Temperature Range, see RETS6121X.
Note 10:
The maximum power dissipation is a function of T
J(max)
,
θ
JA
, and T
A
. The maximum allowable power dissipation at any ambient temperature is P
