Features
Key features of the TS555IDT include a very low supply current, typically 110 µA at 5 V, and a wide frequency range, making it suitable for low-power and battery-operated devices. The TS555IDT also offers high output drive capability and can source or sink up to 100 mA, which allows it to directly drive LED displays or other devices without the need for additional components.
It is designed for improved precision, with reduced timing errors compared to standard 555 timers. The TS555IDT is generally used in applications such as pulse generation, timing delays, and oscillator circuits, benefiting from its enhanced stability and low power characteristics.
Pinout
1. GND (Pin 1): Ground reference voltage, connected to the negative side of the power supply.
2. Trigger (Pin 2): When this pin voltage drops below 1/3 of the supply voltage, it causes the output to go high if the flip-flop is set.
3. Output (Pin 3): Provides the timer's output signal. It can drive TTL inputs and source or sink current.
4. Reset (Pin 4): Resets the flip-flop controlling the output state. It is active-low, meaning it will reset the timer when the voltage is below a certain level.
5. Control Voltage (Pin 5): Allows the modification of the threshold and trigger levels, typically connected to a capacitor for noise filtering.
6. Threshold (Pin 6): When this pin's voltage exceeds 2/3 of the supply voltage, it resets the flip-flop, causing the output to go low.
7. Discharge (Pin 7): Open collector output, usually used to discharge a capacitor between timing intervals.
8. VCC (Pin 8): The supply voltage pin, connected to the positive side of the power supply.
The TS555IDT is utilized in various applications, including monostable, astable, and bistable modes.
