NA556DR TI Programmable Timers and Oscillators

The NA556 is a dual precision timing circuit (two independent 555 timers in a single package), specified for military temperature range of –55°C to 125°C. It operates from 4.5 V to 16 V supply and features high current output of 200 mA sink or source. The device provides 1% timing accuracy and adjustable duty cycle, with maximum frequency of 100 kHz. Each timer can operate in both monostable and astable modes. Packaged in 14-pin SOIC, the NA556 is designed for high-reliability applications. Selection is ideal for precision timing in military, aerospace, and industrial systems requiring dual timers with extended temperature range. Applications include pulse generation, time-delay circuits, frequency division, pulse-width modulation (PWM), missing pulse detection, and oscillator circuits in defense systems, industrial controls, and high-reliability electronics.
