Product Introduction

Overview

The TS555IDTTR is a low-power single CMOS timer produced by STMicroelectronics. It is designed to offer very low power consumption and high frequency capabilities, making it an efficient alternative to traditional bipolar timers like the NE555. The TS555IDTTR operates with a typical supply current of 110 µA at 5 V and 90 µA at 3 V, significantly lower than the NE555. It also features a high maximum astable frequency of 2.7 MHz, which is substantially higher than the NE555's 0.1 MHz. This timer is pin-to-pin functionally compatible with the NE555, making it easy to integrate into existing designs.
