MC14539B Dual 4-Channel Data Selector/Multiplexer
The MC14539B data selector/multiplexer is constructed with MOS P–channel and N–channel enhancement mode devices in a single monolithic structure. The circuit consists of two sections of four inputs each. One input from each section is selected by the address inputs A and B. A “high” on the Strobe input will cause the output to remain “low”. This device finds primary application in signal multiplexing functions. It permits multiplexing from N–lines to I–line, and can also perform parallel–to– serial conversion. The Strobe input allows cascading of n–lines to n–lines. Supply Voltage Range = 3.0 Vdc to 18 Vdc Capable of Driving Two Low–Power TTL Loads or One Low–Power Schottky TTL Load Over the Rated Temperature Range MAXIMUM RATINGS* (Voltages Referenced to VSS)
