The CD74HCT251E is an 8-Input Multiplexer with three-state outputs, designed for high-speed digital applications. It enables selection of one of eight data inputs (I0-I7) based on the combination of three select inputs (S0, S1, S2), making it ideal for data routing, memory addressing, and logic switching.
With a voltage supply range of 4.5V to 5.5V, this multiplexer is compatible with standard TTL logic levels, making it suitable for direct interfacing with LSTTL and CMOS logic families. The device features both true and complement outputs (Y and Y'), providing flexibility in logic circuit designs.
The three-state output function (OE) allows the device to be disabled when not in use, reducing power consumption and enabling multiple devices to share a data bus. The typical propagation delay of 14ns ensures high-speed operation for industrial automation, computing, and communication systems.
Encased in a PDIP-16 package, the CD74HCT251E is widely used in multiplexing, data selection, and memory decoding applications where fast and reliable digital signal routing is required.
