ON Semiconductor MC74AC253D Dual 4-Input Multiplexer with 3-State Outputs

The MC74AC253D is a high-performance integrated circuit designed and manufactured by ON Semiconductor, a leading provider in the semiconductor industry. This dual 4-input multiplexer features 3-state outputs, making it an ideal choice for routing digital signals within a wide array of electronic applications, including computing, networking, and industrial systems.

The device allows two separate data sources to be selected for each multiplexer, providing the flexibility necessary for complex digital switching tasks. Each multiplexer has four binary control inputs (A, B, C, and D) and two select inputs (Select1 and Select2) that determine which of the data inputs will be routed to the output.

The MC74AC253D is characterized by its fast switching performance and low power consumption, which are critical for high-speed digital systems. The 3-state outputs allow for connection to common data or bus lines, which is essential for bus-oriented systems. When the enable input (G) is high, the outputs are in the high-impedance state, effectively isolating the outputs from the bus line.

Key features of the MC74AC253D include:

• Compatible with the industry-standard 'AC' series of logic chips
• High-speed operation, ensuring quick data routing
• Low power dissipation for energy-efficient designs
• Multiple package options for design flexibility
• 3-state outputs to prevent bus contention
• Wide operating voltage range to accommodate various system requirements
• Industrial operating temperature range, making it suitable for harsh environments

The MC74AC253D comes in a SOIC-16 package, which is a small-outline package that saves space on printed circuit boards (PCBs) while still providing excellent thermal and electrical performance. This device is fully compatible with TTL logic levels, which allows for easy integration into existing designs that use TTL logic.

Whether you are designing a complex data routing system or simply need a reliable multiplexer for your digital application, the ON Semiconductor MC74AC253D offers the performance, reliability, and quality that engineers and designers have come to expect from ON Semiconductor products.
