TLC555QDRQ1 Description

Short technical summary and product information.

The TLC555-Q1 is a CMOS monolithic timing circuit from Texas Instruments, suitable for automotive applications. It operates at frequencies up to 2MHz and is functionally interchangeable with the NE555, featuring the same pinout.

 

This timer IC supports single-supply operation from 2V to 15V and consumes very low power, typically 1mW at 5V. Its CMOS output can swing rail-to-rail, and it offers high output current capability, sinking 100mA and sourcing 10mA. The device operates across a temperature range of -40°C to 125°C.

 

Designed for high input impedance, the TLC555-Q1 allows for smaller timing capacitors, enabling more accurate time delays and oscillations compared to the NE555. It is AEC-Q100 qualified for automotive applications and is available in an 8-SOIC package.

 

The timer has trigger and threshold levels at approximately one-third and two-thirds of the supply voltage, respectively, which can be adjusted via the control voltage pin. The reset input can override all other inputs to initiate a new timing cycle.
