TLC556ID

Overview

The TLC556ID is a dual timer integrated circuit manufactured by Texas Instruments, belonging to the LinCMOS™ series. It integrates two independent 555-type timers within a single 14-SOIC package. The device operates on a supply voltage range of 3V to 15V with a typical supply current of 720 µA. It supports frequencies up to 2.1MHz and functions reliably across an industrial temperature range of -40°C to +85°C. This component is designed for surface-mount installation, offering low power consumption compared to bipolar counterparts while maintaining standard 555 timer functionality.

Feature Summary

• Dual 555-type timers integrated in a compact 14-SOIC package
• Low supply current of 720 µA utilizing LinCMOS™ technology
• Operating frequency capability up to 2.1MHz
• Extended industrial temperature range from -40°C to +85°C

Applications

• Precision timing circuits requiring dual channels
• Pulse width modulation (PWM) generation
• Sequential timing events
• Time delay oscillators

Part Context

The TLC556ID is part of the broader TLC556 family of dual CMOS timers. It serves as the industrial-grade, surface-mount variant of the dual timer, contrasting with commercial grade options like the TLC556CD or through-hole packages such as the TLC556IN. The 'I' suffix denotes the extended temperature rating suitable for harsher environments.

Replacement Considerations

For direct pin-compatible replacements, consider the TLC556CDR for commercial temperature applications or the NE556DR for bipolar equivalents. Verify that the substitute component meets the specific -40°C to +85°C operating requirement if industrial grade performance is necessary.
