Overview
The Texas Instruments SN74HC253NG4 is a dual 4-line to 1-line data selector/multiplexer integrated circuit. It is part of the 74HC series, known for its wide operating voltage range and high-current inverting outputs. This device contains two independent data selectors/multiplexers with full binary decoding to select 1-of-4 data sources. It features strobe-controlled (OE) 3-state outputs, which can interface with and drive data lines of bus-organized systems. The SN74HC253NG4 is supplied in a 16-DIP (0.300", 7.62mm) package and is suitable for through-hole mounting.
