TLC555QDRG4 Description

Short technical summary and product information.

The TLC555QDRG4 is a high-performance CMOS timer IC manufactured by Texas Instruments. This general-purpose timer operates in astable mode and is functionally interchangeable with the NE555, featuring the same pinout. It supports single-supply operation from 2V to 15V and consumes very low power, typically 1mW at 5V.

 

With a maximum frequency of 2.1MHz, the TLC555QDRG4 provides a CMOS output capable of swinging rail-to-rail. It offers high output current capability, sinking up to 100mA and sourcing 10mA. Its high input impedance allows for smaller timing capacitors compared to older NE555 or LM555 devices, enabling more accurate time delays and oscillations.

 

This timer IC is compatible with CMOS, TTL, and MOS logic. It is available in an 8-SOIC package, suitable for surface mounting. The device is rated for an operating temperature range of -40°C to 125°C, making it suitable for various environmental conditions. ESD protection exceeds 1000V per ANSI/ESDA/JEDEC JS-001.

 

Applications include configuration control, print support, and high-reliability automotive applications, with qualification to automotive standards available for specific variants.
