Additional Details

The PI74FCT157TPC is a quad 2-input multiplexer consisting of four independent 2-to-1 multiplexers housed in a single package. Each multiplexer selects data from either input A or input B and routes the selected data to the corresponding output, controlled by the select input (S). The device features three-state outputs, enabling easy interfacing with shared bus systems. These outputs are controlled by the output enable (OE) input. When OE is low, the outputs are enabled, and when OE is high, the outputs are in a high-impedance state, preventing bus contention.

This multiplexer is designed for high-speed operation with minimal power consumption, making it suitable for diverse digital system applications. Its TTL-compatible inputs ensure seamless integration with various logic devices. The PI74FCT157TPC is provided in a DIP (Dual In-line Package), which is beneficial for breadboarding and through-hole PCB designs. It finds usage in scenarios such as data selection, logic function generation, and memory address selection. The high-speed performance allows for efficient data handling in time-critical applications. Consolidating four multiplexers into one package helps reduce the component count and simplifies the system layout.
