Overview
The NA556, NE556, SA556, and SE556 are dual precision timers that provide two independent timing circuits in a single package.
Features
These devices offer astable or monostable operation, TTL-compatible output, and can sink or source up to 150 mA. They are designed to be interchangeable with Signetics NE556, SA556, and SE556.
Applications
The NA556, NE556, SA556, and SE556 are suitable for a wide range of applications, including precision timers, pulse-shaping circuits, missing-pulse detectors, tone-burst generators, pulse-width modulators, pulse-position modulators, sequential timers, pulse generators, frequency dividers, and application timers in industrial controls and touch-tone encoders.
