NE556DR Description

Short technical summary and product information.

The NE556DR is a dual precision timer integrated circuit manufactured by Texas Instruments. This component is designed for general-purpose timing applications and can operate in astable or monostable modes.

Key electrical specifications include an operating voltage range of 4.5V to 16V and a typical supply current of 20 mA. The device offers a frequency output of 100kHz. The operating temperature range for this timer is from 0°C to 70°C.

Packaged in a 14-SOIC (0.154", 3.90mm Width) surface-mount configuration, the NE556DR is suitable for various electronic designs. It provides two independent timing circuits per package, with TTL-compatible outputs capable of sinking or sourcing up to 200mA. Unused inputs should be tied to an appropriate logic level to prevent false triggering.
