TLC556CD

Overview

The TLC556CD is a dual CMOS timer integrated circuit manufactured by Texas Instruments. It integrates two independent 555-type timers within a single SOIC-14 package. The device operates on a supply voltage range of 2 V to 15 V and supports a maximum frequency of 2.1 MHz. It features high output drive capabilities with a low-level output current of 100 mA. The component is designed for surface-mount installation and functions reliably within an operating temperature range of 0 °C to +70 °C.

Feature Summary

• Dual timer configuration in a compact SOIC-14 package
• CMOS technology ensuring low power consumption
• High output drive capability with 100 mA sink current
• Wide supply voltage operation from 2 V to 15 V

Applications

• Timing and pulse generation circuits
• Oscillator applications
• Sequential timing events
• Time delay generation

Procurement Notes

Verify the specific suffix 'CD' corresponds to the commercial grade temperature range (0°C to +70°C) and SOIC-14 tube packaging. Confirm RoHS compliance status as indicated in official datasheets. Ensure the ordering part number matches the required package style and temperature rating before procurement.

Selection Notes

Select the TLC556CD when dual independent timers are required in a surface-mount design. Compare against the single-timer TLC555CD if only one channel is needed. Verify that the 2.1 MHz maximum frequency meets the application requirements. Ensure the 2 V to 15 V supply range aligns with the system power rails.

Part Context

The TLC556CD belongs to the TLC556 series of dual CMOS timers from Texas Instruments. It serves as a complementary component to the single-channel TLC555CD. Both devices share similar electrical characteristics but differ in the number of integrated timers and pin count, with the TLC556CD utilizing a 14-pin SOIC package.
