The LMC6008 octal buffer is designed specifically to buffer the multi-level voltages going to the inputs of the integrated circuits. The LMC6008 AC characteristics, including settling time, are specified for a capacitive load of 0.1 mF. The LMC6008 contains 4 high-speed buffers and 4 low-power buffers. The high-speed buffers can provide an output current of at least 250 mA (minimum), and the low-power buffers can provide at least 150 mA (minimum). By including the 2 types of buffers, the LMC6008 is able to provide this function while consuming a supply current of only 6.5 mA (maximum). The buffers are a rail-to-rail design, which typically swing to within 30 mV of either supply. The LMC6008 also contains a standby function which puts the buffer into a high-impedance mode. The supply current in the standby mode is a low 500 mA max. Also, a thermal limit circuit is included to protect the device from overload conditions.

LMC568 is a low power Phase-Locked Loop chip produced by National Semiconductor Corporation. It supports ±15% FM and FSK signal demodulation, with a maximum input frequency of 500kHz. Typical application scenarios include FM SCA and TV second audio program decoders, FSK data demodulators and voice pagers.

The LMC567 is a low power general purpose LMCMOS™ tone decoder which is functionally similar to the industry standard LM567. It consists of a twice frequency voltage-controlled oscillator (VCO) and quadrature dividers which establish the reference signals for phase and amplitude detectors. The phase detector and VCO form a phase-locked loop (PLL) which locks to an input signal frequency which is within the control range of the VCO. When the PLL is locked and the input signal amplitude exceeds an internally pre-set threshold, a switch to ground is activated on the output pin. External components set up the oscillator to run at twice the input frequency and determine the phase and amplitude filter time constants.

The LMC555 is a CMOS version of the industry standard 555 series general purpose timers.
