Texas Instruments TLC556M Low-Power Dual LinCMOS<TM> Timer TLC556MJB

The TLC556M is a low-power dual timer from Texas Instruments, designed using the LinCMOS,Ñ¢ process, which ensures compatibility with CMOS, TTL, and MOS logic. It operates over a wide supply voltage range of 2V to 15V and is characterized for military temperature ranges from -55¬8C to +125¬8C. The device features a typical power consumption of 2mW at 5V and can operate in astable mode, making it suitable for various timing applications such as pulse generation, sequential timing, and time delay generation. The TLC556M offers high output-current capability, with a sink current of 100mA and a source current of 10mA, while maintaining low supply current spikes during output transitions. This characteristic reduces the need for large decoupling capacitors compared to similar devices. The timer supports operation at frequencies up to 2MHz and allows for precise timing with smaller timing capacitors due to its high input impedance. The device is functionally interchangeable with the NE556, sharing the same pinout, which facilitates easy integration into existing designs.
