The TLC555QDR is a TimerBlox CMOS timer with Texas Instruments Timers & Support Products manufactured by Texas Instruments. It is a low-power CMOS timer designed for single-supply applications. The device can be used in a variety of applications like frequency divider, on-delay or off-delay timing, clock switching, pulse generation and generation of PWM signals. Its low power operation makes it well suited for battery-backed, battery-only and other types of portable applications. It operates on VDD supply voltages of 2.3V to 15V. It features an on-board digital-to-analog converter (DAC) pin and an on-chip RC oscillator for selectable frequency dividers from 1 to 512. The device also features low output-to-input propagation delay for precise timing and a high-output current drive for faster operation. It is a highly reliable device offering industry-leading levels of performance, which makes it ideal for use in automotive and consumer applications.
