F/FAST multiplexer, 1-of-8 data selector
The 54F151ADC is a Texas Instruments F/FAST Series 1-of-8 multiplexer — a data selector that routes one of eight input lines to a single output based on a three-bit address. The F/FAST family is a bipolar logic series optimized for speed, with typical propagation delays in the low-nanosecond range, making this part suited for high-speed data routing in processor and memory interface applications. Listed under the Microcontrollers & Processors (MCU / MPU / DSP) category, the 54F151ADC serves as a glue-logic component for address decoding, data bus multiplexing, and signal routing in digital systems.
