Ground to Negative Supply Voltage ........................ 25V
Ground to Positive Supply Voltage ......................... 18V
Diffierential Input Voltage ....................................... ±5V
Differential Input Current ...................................... ±5mA
Input Voltage (See Note 1)
Output Short-Circuit Duration ............................. 10 sec
Operating Temperature Range .............. – 55°C to 125°C
Storage Temperature Range ................. – 65°C to 150°C

The RH119 is capable of operation over a supply range
from 5V to ±15V and can drive 25mA loads from each open
collector output. A separate GND pin allows the RH119 to
isolate system grounds.
The wafer lots are processed to Linear Technology’s inhouse Class S flow to yield circuits usable in stringent
military applications.

ELECTRICAL CHARACTERISTICS
(Continued)
Note 1: For supply voltages less than ±15V, the maximum input voltage is
equal to the supply voltage.
Note 2: Unless otherwise noted, supply voltage equals ±15V, VCM = 0V
and TA = 25°C. The GND pin is grounded. Note that the maximum voltage
allowed between the GND pin and V + is 18V. Do not tie the GND pin to V –
when the power supply voltage exceeds ±9V. The offset voltage, offset
current and bias current specifications apply for all supply voltages
between ±15V and 5V unless otherwise specified.
Note 3: The offset voltages and currents given are the maximum values
required to drive the output within 1V of either supply with a 1mA load––
thus, these parameters define an error band and take into account the
worst-case effects of voltage gain and input impedance.
Note 4: Response time specified for a 100mV input step with 5mV
overdrive.
Note 5: VS = ±15V, VCM = 0V, TA = 25°C unless otherwise noted.

PDA Test Notes
The PDA is specified as 5% based on failures from group A, subgroup 1,
tests after cooldown as the final electrical test in accordance with method
5004 of MIL-STD-883 Class B. The verified failures (including Delta
parameters) of group A, subgroup 1, after burn-in divided by the total
number of devices submitted for burn-in in that lot shall be used to
determine the percent for the lot.
Linear Technology Corporation reserves the right to test to tighter limits
than those given.
