Key Features
- Dual independent timer channels in a single 14-pin DIP package, reducing BOM count for multi-timer designs
- Wide supply voltage range from 2 V to 15 V enabling use in both low-power battery and standard 5 V/12 V systems
- Output frequency capability up to 2 MHz for pulse generation, PWM, and frequency division applications
Applications
The TS556IN is used in pulse generation, PWM motor control, and oscillator circuits where two independent timing channels are required in a single package. Operating from 2 V to 15 V, it fits battery-powered consumer devices as well as industrial 12 V control panels. System designers use it for clock generation, tone generation, and sequential timing logic in embedded control boards.

Frequently Asked Questions
What supply voltage range does the TS556IN support, and how does this affect battery-powered designs?
The TS556IN operates across a wide supply voltage range from 2 V to 15 V. This flexibility allows engineers to power it directly from a single 3 V coin cell in handheld devices or a 12 V rail in automotive and industrial panels without requiring a voltage regulator stage, simplifying the overall power supply design.
Up to what output frequency can the TS556IN be configured in astable mode, and what applications benefit from this?
In astable mode, the TS556IN can generate output frequencies up to 2 MHz. This makes it suitable for PWM generation in DC motor speed control, LED dimming circuits, and clock signal synthesis where a simple RC-based 2 MHz oscillator replaces a dedicated crystal or clock generator, reducing component cost.
When would a designer choose TS556IN over two discrete NE555 ICs in a 14-pin DIP footprint?
The TS556IN integrates 2 independent timer channels in a single 14-pin DIP package, directly replacing two separate NE555 ICs that would each require an 8-pin package. This halves the number of timer ICs, reduces PCB area, lowers assembly cost, and simplifies routing for dual-timing designs such as sequential relay drivers or two-phase oscillators.
