3-to-8 line decoder, demultiplexer with address latches

1. General description The 74HC237 is a 3-to-8 line decoder, demultiplexer with latches at the three address inputs (An). The 74HC237 essentially combines the 3-to-8 decoder function with a 3-bit storage latch. When the latch is enabled (LE = LOW), the 74HC237 acts as a 3-to-8 active LOW decode
