16-Channel Analog Multiplexer/Demultiplexer IC - CD4067 CD4067 CMOS analog multiplexers/demultiplexers are digitally controlled analog switches having low ON impedance, low OFF leakage current, and internal address decoding. In addition, the ON resistance is relatively constant over the full input-signal range. The CD4067 is a 16-channel multiplexer with four binary control inputs, A, B, C, D, and an inhibit input, arranged so that any combination of the inputs selects one switch. A logic “1” present at the inhibit input turns all channels off. The CD4067 type are supplied in 24-lead hermetic dual-in-line ceramic packages (F3A suffix), 24-lead dual-in-line plastic packages (E suffix), 24-lead small-outline packages (M, M96, and NSR suffixes), and 24-lead thin shrink small-outline packages (P and PWR suffixes). check out : CD4066 - Quad Bilateral Switch IC Applications: Analog and digital multiplexing and demultiplexing A/D and D/A conversion Signal gating

16MHz Crystal Oscillator - (Pack of 5) The 16 MHz crystal oscillator circuit sustains oscillation by taking a voltage signal from the quartz resonator, amplifying it, and feeding it back to the resonator. It provides clock pulses of 8 MHz frequency. The popularity of the crystals is due to the low cost. How are crystal oscillators useful? One of the most important traits of the crystal oscillator is that it exhibits very low phase noise. In the crystal oscillator, the crystal mostly vibrates in one axis, therefore only one phase is dominant. This property of low phase noise makes them particularly useful in telecommunications where stable signals are needed, and in scientific equipment where very precise time references are needed. The result is that a quartz crystal behaves like a circuit composed of an inductor, capacitor and resistor, with a precise resonant frequency. Also check pack of 10 32.768KHz Crystal Oscillators available on the Iotcart website. Each oscillator provides clock pulses with a frequency of 8 MHz. The crystal oscillator can be utilized as a UART clock (6×1.8432 MHz) and allows integer division to common baud rates. Also check 12MHz Crystal Oscillator, sold in a pack of 10 on the Iotcart website. This crystal oscillator is commonly used in various electronic applications, including as a clock for AVR microcontrollers, in microprocessor clocks, network cards, and other consumer electronics.
