Description

The LM211, LM311 are voltage comparators that have low input currents. They are also designed to operate over a wide range of supply voltages: from standard ±15 V operational amplifier supplies down to the single +5 V supply used for IC logic. Their output is compatible with RTL-DTL and TTL as well as MOS circuits and can switch voltages up to +50 V at output currents as high as 50 mA.

2 Absolute maximum ratings & operating conditions

Table 2. Absolute maximum ratings (AMR)

  1. This rating applies for ±15V supplies. The positi ve input voltage limit is 30V above the negative. T he
  2. P d is calculated with T amb = +25°C, T j = +150°C and R thja = 175°C/W for the SO-8 package.
