Product Summary
The HD74HC237FPEL is a 3-to-8-line Decoder/Demultiplexer with Address Latch. The HD74HC237FPEL decodes a three-bit Address to one-of-eight active-high outputs. The HD74HC237FPEL has a transparent latch for storage of the Address. Two Chip Selects, one active-low and one active-high, are provided to facilitate the demultiplexing, cascading, and chip-selecting functions. The demultiplexing function is accomplished by using the Address inputs to select the desired device output, and then by using one of the Chip Selects as a data input while holding the other one active.
