The Texas Instruments TLC556IDR is a dual LinCMOS timer integrated circuit designed for timing and oscillation applications. It operates over a wide supply voltage range of 3V to 18V and supports frequencies up to 2.1MHz.
This timer IC features very low power consumption, typically 2mW at 5V, and a CMOS output capable of swinging rail to rail. It offers high output current capability, sinking 100mA and sourcing 10mA. The TLC556IDR is functionally interchangeable with the NE556 and shares the same pinout, making it a suitable drop-in replacement with upgraded functionality.
Designed for surface mounting, the TLC556IDR comes in a 14-SOIC package. Its high input impedance allows for the use of smaller timing capacitors compared to the NE556, enabling more accurate time delays and oscillations. The device is compatible with CMOS, TTL, and MOS logic.
Key specifications include an operating temperature range of -40°C to 85°C and a low supply current. The trigger and threshold levels are approximately one-third and two-thirds of the supply voltage, respectively, and can be adjusted using the control voltage pin.
