Exploring Different Types of Integrated Circuits: Part 15

 Integrated circuits (ICs) have revolutionized the world of electronics by making it possible to pack complex circuits into small chip. With the increasing demand for miniaturization and efficient designs, ICs have become an essential component in modern electronics. In this blog, we will discuss three types of integrated circuits: 74HC123 Dual Retriggerable Monostable Multivibrator IC, 74HC125 Quad Tri-state Buffer IC, and 74HC126 Quad 3-State Buffer IC.

74HC123 Dual Retriggerable Monostable Multivibrator IC

The 74HC123 is a dual retriggerable monostable multivibrator IC that is used for pulse shaping, precision timing, and waveform generation applications. It is a 16-pin IC with two independent monostable multivibrators in a single package. The IC has two trigger inputs, one of which can be used as a retrigger input. The output pulse width is controlled by an external capacitor and resistor connected to its timing pin. The 74HC123 is compatible with both TTL and CMOS logic and has a wide range of operating voltage from 2V to 6V.

74HC125 Quad Tri-state Buffer IC

The 74HC125 is a quad tri-state buffer IC that is used for signal buffering, level translation and driving capacitive loads. It is a 14-pin IC with four independent tri-state buffers in a single package. The IC has a high-impedance input and can be driven by either TTL or CMOS logic. The output is a standard TTL logic level, and the IC can drive loads up to 15 pF. The tri-state feature of the IC allows multiple outputs to be connected together without any conflict, and the outputs can be disabled when not in use.

74HC126 Quad 3-State Buffer IC

The 74HC126 is a quad 3-state buffer IC that is used for signal buffering, data routing, and driving capacitive loads. It is a 14-pin IC with four independent 3-state buffers in a single package. The IC has a high-impedance input and can be driven by either TTL or CMOS logic. The output is a standard TTL logic level, and the IC can drive loads up to 15 pF. The 3-state feature of the IC allows the outputs to be disabled when not in use, making it ideal for bus-oriented applications.
