Introduction

The SN75158D component is an integrated circuit used in variety of electronic devices, providing two receivers and one driver for TTL (Transistor-Transistor Logic). It is an ideal component for bidirectional data and address buffering on a single bus. Though there are many differences between this component and the TTL family of integrated circuits, it uses the same 5-volt power supply which offers a degree of compatibility with the TTL family.

Application Field

The SN75158D component offers two data buses, making it ideal for applications in data transfer and communication. It is often used in electronic logic circuits, as a bidirectional buffer. Additionally, the component can be used in many different types of applications, such as microprocessor control systems, communication systems, and data processing systems. It is also used in consumer electronics, including video game consoles, portable media players, and digital cameras.

Working Principle

The SN75158D component is powered by a 5-volt power supply. Its circuit consists of two open-drain outputs, and one active-Low output. The two open-drain outputs are connected to two output ports via two transistors, making it easy to drive either of the ports with the same logic level. When the transistor is enabled, the logic level in either output port is determined by the power supply voltage. The active-low output activates when the power supply voltage is below the preset threshold level. The circuit also contains two resistors and a capacitor, which help it in driving the outputs into their correct states.
