Features
• Low input offset current — 4 nA
• Low input bias current — 60 nA
• Operates from a single +5V supply
• Response Time — 200 ns
Description
These low input current voltage comparators are designed to
operate over a wide range of supply voltages, including
+15V and single +5V supplies. Their outputs are compatible
with DTL, RTL, TTL and MOS devices, and can be con-
nected in “wire-OR” configuration. The LH2111 consists of
two LM111 ICs packaged in a 16-lead DIP. The LH2111 is
available with MIL-STD 883B screening.

Notes:
1. VOS, IOS and IB specifications apply for VS = +5V to VS = ±15V.
2. VOS and IOS are maximum values required to drive the output to within 1V of either supply with a 1 mA load.
3. Do not short circuit the strobe pin to ground—drive it with a 3 to 5 mA current Instead.
4. If the strobe and balance pins are unused, short them together for maximum AC stability.
