The NE5568N from NXP Semiconductors is a highly versatile dual precision timer IC that is capable of producing accurate time delays or oscillation. It is the dual version of the well-known 555 timer IC and features two independent 555 timers in a single package, providing more functionality while saving space on the PCB.

Key Features

• Supply Voltage: The NE5568N operates on a wide range of supply voltages from +4.5V to +16V, making it suitable for various applications and compatible with TTL logic levels.
• Output Drive Capability: It can drive TTL loads and can source or sink up to 200mA, allowing it to directly drive small relays, lamps, and other loads.
• Dual Timer: The dual timer configuration allows for sequential timing, interval timing, pulse width modulation (PWM), and other time-related functions, all within a single IC.
• Adjustable Duty Cycle: The timers offer an adjustable duty cycle, giving the user control over the signal's pulse width.
• High Current Output: The high current output can drive loads directly without additional transistors.
