Key Features
- 1.2 MHz maximum output frequency in CMOS LinCMOS process enables higher-speed astable and monostable operation compared to standard bipolar 555 timers at 300 kHz
- Rail-to-rail output swing and microampere-level supply current make the TLC555IP-P2 ideal for battery-powered timing circuits where the classic NE555 consumes too much power
- 8-pin PDIP through-hole package provides drop-in functional compatibility with NE555 and LM555 pinout, allowing direct upgrade to CMOS performance in existing designs
Applications
The TLC555IP-P2 is used in pulse-width modulation, LED flasher circuits, and precision monostable timing applications where CMOS low-power operation and higher frequency capability over the standard bipolar 555 are required. It also suits oscillator, tone generator, and waveform shaping circuits in 2.1 V to 15 V battery-operated systems such as portable instruments and IoT sensor nodes.

Frequently Asked Questions
How does the TLC555IP-P2's maximum frequency of 1.2 MHz compare to the standard bipolar NE555?
The TLC555IP-P2 operates as an astable oscillator up to 1.2 MHz, which is approximately 4 times higher than the 300 kHz typical maximum of the bipolar NE555. The CMOS LinCMOS process also reduces supply current from about 10 mA in the NE555 to under 1 mA at 5 V, making the TLC555 significantly more efficient in frequency-sensitive or battery-powered applications.
What supply voltage range does the TLC555IP-P2 support, and is it compatible with 3.3 V systems?
The TLC555IP-P2 operates from 2.1 V to 15 V, covering both 3.3 V and 5 V microcontroller supply rails without additional regulation. At 3.3 V supply the output swings within a few millivolts of each rail, and timing accuracy with RC networks remains within the 1% to 2% typical tolerance of the external resistor and capacitor values.
What timing formula applies to the TLC555IP-P2 in monostable mode, and what external components set the pulse width?
In monostable mode the TLC555IP-P2 output pulse width is set by t = 1.1 x R x C, where R is the timing resistor and C is the timing capacitor. For example, a 100 kohm resistor with a 10 nF capacitor gives a pulse width of 1.1 ms. The TLC555 is pin-compatible with the NE555 so existing monostable designs can be directly upgraded.
Can the TLC555IP-P2 replace a 556 dual-timer IC in a two-channel timing circuit?
The TLC555IP-P2 is a single-channel timer in an 8-pin PDIP, so two TLC555IP-P2 devices are needed to replace a dual 556. Each TLC555 occupies a DIP-8 footprint of approximately 9.7 mm x 6.4 mm. However, using 2 separate TLC555 devices allows independent supply bypassing and eliminates cross-talk between channels that can occur in a shared-package dual timer at frequencies above 100 kHz.
