The MC74HC237N is a high-speed CMOS 3-to-8 line decoder/demultiplexer with integrated address latches. This device is designed to accept three binary weighted inputs (A0, A1, A2) and, when enabled, provides eight mutually exclusive active HIGH outputs (Y0–Y7). The internal latches allow the device to store the address information, enabling the outputs to remain stable even if the input data changes.
With multiple input enable options, the MC74HC237N offers flexibility in circuit design, allowing for easy expansion or independent control of multiple devices. The active HIGH outputs ensure that only one output is active at any given time, making it ideal for applications such as memory chip selection, where precise control is crucial.
Built using high-speed silicon-gate CMOS technology, this decoder/demultiplexer operates efficiently with low power consumption. Its standard output capability ensures compatibility with various logic families, and the DIP-16 package facilitates straightforward integration into printed circuit boards.
Common applications for the MC74HC237N include memory address decoding, data routing, and enabling specific devices within larger digital systems. Its combination of address latching and decoding functions makes it a versatile component in digital circuit design.
