The TLC556CD from Texas Instruments is a dual CMOS timer IC belonging to the 555 timer family. It is designed for general-purpose timing and oscillation applications, operating across a wide supply voltage range of 2V to 18V.
This timer IC features a maximum operating frequency of 2.1MHz and a low quiescent current of 720 µA. It is specified for operation within a temperature range of 0°C to 70°C. The TLC556CD offers high output current capability, sinking up to 100mA and sourcing 10mA.
Packaged in a 14-SOIC surface-mount format, the TLC556CD is functionally interchangeable with the NE556 and offers improved performance characteristics such as lower power consumption and reduced supply current spikes. Its high input impedance allows for smaller timing capacitors, enabling more accurate time delays and oscillations.
Key electrical characteristics include a trigger level at approximately one-third of the supply voltage and a threshold level at approximately two-thirds, which can be adjusted via the control voltage pin. The reset input overrides all other inputs to initiate a new timing cycle.
