M74HC238, 3 TO 8 LINE DECODER

The M54/74HC238 is a high speed CMOS 3 to 8 line 2 decoder fabricated in silicon gate C MOS technology.

It has the same high speed performance of LSTTL combined with true CMOS low power consumption.

If the device is enabled, 3 binary select inputs (A, B and C) determine which one of outputs will go
