74258 Quad 2-input multiplexer 5V 9mA IC DIP-16

From the shop's description

74258 Quad 2-input multiplexer 5V 9mA IC DIP-16 The 74258 is a Quad 2-Input Multiplexer integrated circuit that contains four independent 2-to-1 multiplexers within a single package. Each multiplexer selects one of two input signals and routes it to the corresponding output based on the common select control line. The device features three-state inverted outputs, making it suitable for bus-oriented systems and digital logic designs. This IC is widely used in microprocessor systems, communication equipment, industrial controllers, and digital switching circuits where multiple data sources must be selected efficiently. Its TTL-compatible operation allows easy integration with other standard 74-series logic devices, making it a versatile component for educational, prototyping, and production applications. Features: Four independent 2-to-1 multiplexers in one IC. Common data select input for all channels. Three-state output capability. Inverting outputs. TTL-compatible logic levels. High-speed switching performance. Suitable for bus-oriented applications. Compatible with standard 74-series logic families. Reliable DIP package for through-hole mounting. Low power consumption for digital logic circuits.
