Data Selector

This document describes the M1701 Data Selector, which incorporates two DEC74153 dual 4-line-to-1-line data selector/multiplexer ICs. These modules serve as input multiplexers within the ALU section of the FP15 Floating-Point Processor. The document provides a truth table for operation, detailing how address inputs A and B select data inputs, and how the strobe input (S) enables the output. Key specifications provided include a typical power dissipation of 170 mW per IC and input/output load characteristics.
