NA556DR TI Dual Timer IC | 14-SOIC | Dual Precision Timers, 4.5V-16V

Product Overview

The NA556DR is a dual precision timer IC from Texas Instruments, integrating two independent 555-type timer circuits in a single 14-pin SOIC package. It offers high timing accuracy and stability over a wide supply voltage range of 4.5V to 16V. Each timer can operate in monostable or astable mode, providing precise time delays or oscillation. The device features low power consumption, high output drive capability, and is fully specified for operation from -40°C to +85°C. Its compact SOIC-14 package makes it ideal for space-constrained applications.
