| RH119 High Performance Dual Comparator DESCRIPTION The RH119 dual comparator features low input offset voltage and offset current, high voltage gain, guaranteed common mode rejection and input protection diodes. The RH119 is capable of operation over a supply range from 5V to 15V and can drive 25mV leads 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. , LTC and LT are registered trademarks of Linear Technology Corporation.

Note 4: Response time specified for a 100mV input step with 5mV overdrive. Note 5: VS = 15V, VCM = 0V, TA = 25C unless otherwise noted. 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 and TA = 25C. 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. TABLE 2: ELECTRICAL TEST REQUIRE E TS MIL-STD-883 TEST REQUIREMENTS Final Electrical Test Requirements (Method 5004) Group A Test Requirements (Method 5005) Group C and D End Point Electrical Parameters (Method 5005) * PDA Applies to subgroup 1. See PDA Test Notes. SUBGROUP 1*,2,3,4 1,2,3,4 1 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.
