Description

NE556D – TI

Description

The NE556D is a dual timer designed for applications where two timers are required. It is pin-for-pin compatible with the NE555, but has several improved features. The NE556D is available in a 14-pin DIP package or a 14-pin SOIC package.

Features

• Dual timer with pin-for-pin compatibility to NE555
• Improved timing stability and accuracy
• High input impedance
• Low supply current
• Compatible with a wide range of TTL and CMOS logic
• Available in 14-pin DIP and 14-pin SOIC packages
