LM311H Description

Short technical summary and product information.

The Thomson-CSF LM311H is a voltage comparator IC known for its low input currents, nearly a thousand times lower than older devices. It operates from standard ±15V op amp supplies down to a single 5V supply suitable for IC logic. The output is compatible with RTL, DTL, TTL, and MOS circuits, and can drive lamps or relays with voltages up to 50V and currents as high as 50 mA.

Key electrical specifications include a maximum input current of 150 nA over temperature, a maximum offset current of 20 nA over temperature, and a differential input voltage range of ±30V. Power consumption is typically 135 mW at ±15V. The operating temperature range is 0°C to 70°C.

This comparator offers flexibility with inputs and outputs that can be isolated from system ground. The output can drive loads referred to ground, the positive supply, or the negative supply. Offset balancing and strobe capability are provided, and outputs can be wire OR'ed. While its response time is 200 ns, it is less prone to spurious oscillations compared to faster devices.

The LM311H is supplied in a TO-CAN (LMC) package with a standard package quantity of 500 units.
