What are the key features of TS555CDT?
- Wide supply range of 2 V to 16 V covering battery-powered and industrial 12 V applications in a single device
- CMOS technology enabling 2 MHz maximum output frequency with lower supply current than bipolar NE555 equivalents
- 8-pin SOIC surface-mount package with pin-compatible NE555 footprint for easy drop-in design replacement
What is TS555CDT used for?
TS555CDT is used in timing, pulse generation, and oscillator circuits for consumer electronics, industrial control, and automotive accessories. Its wide 2 V to 16 V supply range makes it suitable for battery-operated portable timers, LED flashers, and motor speed controllers without additional regulation. The CMOS process reduces quiescent current compared to bipolar 555 variants, extending battery life in low-duty-cycle timing applications.

Frequently Asked Questions
What supply voltage range does TS555CDT support, and how does this compare to a standard NE555?
TS555CDT operates from 2 V to 16 V, whereas the standard bipolar NE555 typically requires 4.5 V to 16 V. This lower minimum supply of 2 V allows TS555CDT to function directly from a single lithium coin cell or two AA batteries, making it preferable in ultra-low-voltage portable timing circuits where the NE555 would fail to start.
What is the maximum oscillation frequency of TS555CDT in astable mode?
TS555CDT can operate in astable mode at frequencies up to 2 MHz, limited by its internal CMOS comparator speed and the RC time-constant network. At 2 V supply the maximum usable frequency is lower, around 200 kHz, but at 5 V and 12 V, 1 MHz to 2 MHz astable operation is achievable with small timing resistors and capacitors in the picofarad range.
In which low-power portable timing or oscillator designs does TS555CDT offer an advantage over bipolar 555 timers?
TS555CDT draws significantly less quiescent current than bipolar 555 timers, typically under 200 µA at 5 V versus 3 mA to 10 mA for NE555, making it well suited for battery-powered alarm timers, sleep-mode wake-up oscillators, and slow-pulse LED flashers. In a 9 V battery design running a 1 Hz astable oscillator, switching from NE555 to TS555CDT can extend battery life by more than 10 times.
Which package does TS555CDT use, and is it pin-compatible with standard DIP-8 NE555 circuits?
TS555CDT uses an 8-pin SOIC (SO-8) surface-mount package with 1.27 mm pin pitch and a 3.9 mm body width, not a through-hole DIP. It is functionally and electrically pin-compatible with the NE555 in SMD form, allowing designers to migrate from through-hole DIP-8 NE555 designs to a more compact SMD footprint without schematic changes, using the same RC component values for identical timing behavior.
