TLC555IP

Overview

The TLC555IP is a single timer integrated circuit manufactured by Texas Instruments using LinCMOS technology. It operates on a single power supply ranging from 2 V to 15 V and supports frequencies up to 2.1 MHz. The device features rail-to-rail CMOS outputs with high drive capability, sourcing 10 mA and sinking 100 mA. It maintains functional compatibility with the NE555 while offering significantly lower power consumption, typically 1 mW at 5 V. The component is housed in an 8-pin DIP package.

Feature Summary

• Low Power Consumption: Typical current draw of 250 µA and 1 mW power dissipation at 5 V.
• High Output Drive: Capable of sinking 100 mA and sourcing 10 mA.
• Wide Voltage Range: Operates reliably between 2 V and 15 V.
• Logic Compatibility: Fully compatible with CMOS, TTL, and MOS logic families.

Applications

• Precision timing circuits
• Pulse generation
• Sequential timing control
• Time delay generation
• PWM (Pulse Width Modulation) controllers

Procurement Notes

Verify the specific suffix 'IP' against the official datasheet to confirm it denotes the PDIP-8 package variant. Ensure the order matches the required operating temperature range, as standard industrial grades typically cover 0°C to +70°C. Confirm RoHS compliance status for the specific manufacturing lot.

Selection Notes

Select this component when low static current is critical compared to bipolar alternatives like the NE555. The high input impedance allows for smaller timing capacitors, enabling more precise delays. Ensure the load requirements do not exceed the 100 mA sink current limit.

Part Context

The TLC555 series represents the CMOS evolution of the classic 555 timer architecture. Utilizing LinCMOS processes, these devices provide higher switching speeds and lower power usage than traditional bipolar versions. The IP suffix specifically identifies the through-hole plastic dual in-line package configuration.

Replacement Considerations

Functionally interchangeable with NE555, LM555, and LMC555. Verify pinout compatibility before substitution. Note that bipolar replacements may require higher supply currents.
