CD74HCT251E TI Multiplexer | 16-PDIP | 8-Channel, High-Speed CMOS

Product Overview

The CD74HCT251E from Texas Instruments is a high-speed CMOS 8-input multiplexer with three-state outputs. It features a 3-bit binary select code (A, B, C) to route one of eight data inputs (I0–I7) to a single output (Y). The device also provides a complementary output (W) and an output enable (OE) input for bus-oriented applications. Operating from a 4.5V to 5.5V supply, it is compatible with TTL logic levels and offers low power consumption. The 16-pin PDIP package ensures easy integration into through-hole designs.
