CD54HC251F

The CD54HC251F from Texas Instruments is a high-speed CMOS logic integrated circuit functioning as an 8-input digital multiplexer with three-state output capability. This device selects one of eight binary data inputs and provides both true and complement outputs. It is fabricated using high-speed silicon-gate CMOS technology, offering significant power reduction compared to LSTTL logic ICs while maintaining the ability to drive up to 10 LSTTL loads.

The multiplexer features a typical data-to-output propagation delay of 14 ns at VCC = 5 V, CL = 15 pF, and TA = 25 ℃. It operates over a wide temperature range from -55 ℃ to 125 ℃, making it suitable for various environmental conditions. The three-state feature makes the CD54HC251F ideal for interfacing with bus lines in bus-oriented systems.

Available in a 16-pin CDIP package with a body size of 24.38 mm x 6.92 mm, this component is designed for applications requiring efficient data selection and bus interfacing. The HC types support a 2 V to 6 V operation with high noise immunity, while HCT types offer direct LSTTL input logic compatibility and CMOS input compatibility.
