Overview
The TLC556IN 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-pin Dual In-Line Package (PDIP). The device operates on a supply voltage range of 3V to 18V and supports a maximum frequency of 2MHz. Designed for surface-mount or through-hole applications depending on the variant, this specific PDIP version is rated for an operating temperature range of -40°C to +85°C. It features low power consumption with a supply current of approximately 720 µA, making it suitable for battery-powered timing circuits.
Feature Summary
- Dual 555-type timers in a single 14-pin PDIP package
- LinCMOS™ technology for low power consumption (720 µA)
- Wide supply voltage range: 3V to 18V
- Operating temperature range: -40°C to +85°C
Applications
- General-purpose timing and pulse generation
- Sequential timing events
- Time delay circuits
- Frequency division
Procurement Notes
Verify the package type carefully when ordering. The suffix 'IN' specifically denotes the 14-pin PDIP (Through-Hole) package. Ensure the design requires through-hole mounting rather than surface mount variants like 'IDR' (SOIC). Confirm the voltage range requirements align with the 3V-18V specification before procurement.
Selection Notes
Select the TLC556IN when dual timer functionality is required in a through-hole compatible package. Compare against the NE556N if TTL-compatible output levels are needed instead of CMOS. Consider the TLC556IDR if surface mount assembly is preferred. Verify that the 2MHz maximum frequency meets the application's timing speed requirements.
Part Context
The TLC556 is part of Texas Instruments' LinCMOS™ family, offering lower power consumption compared to standard bipolar 556 timers like the NE556. It serves as a dual-channel alternative to the single-channel TLC555. The 'IN' suffix distinguishes it from other packaging options within the same electrical specification family.
Replacement Considerations
NE556N (TTL output, different power specs), TLC556IDR (Surface Mount SOIC equivalent), SA556NE4 (Discontinued, TTL output).
