The Texas Instruments TLC556CDR is a versatile dual timer IC belonging to the 555 timer family, designed for general-purpose timing and oscillation applications. It operates from a wide supply voltage range of 2V to 15V and can achieve frequencies up to 2.1MHz. This device features very low power consumption, typically 2mW at 5V, and a CMOS output capable of rail-to-rail swing.
The TLC556CDR offers high output current capability, sinking up to 100mA and sourcing 10mA. Its high input impedance allows for smaller timing capacitors compared to the NE556, enabling more accurate time delays and oscillations. The output is fully compatible with CMOS, TTL, and MOS logic levels. The device is housed in a compact 14-SOIC surface-mount package, making it suitable for various electronic designs.
Key electrical characteristics include a typical supply current of 0.13mA at 5V and a maximum frequency of 2.1MHz. The trigger level is approximately one-third of the supply voltage, and the threshold level is approximately two-thirds, adjustable via the control voltage pin. Tie unused inputs to an appropriate logic level to prevent false triggering.
