M74HCT258
DESCRIPTION
The M74HCT258 is an high speed CMOS QUAD 2 CHANNEL MULTIPLEXER (3-STATE) fabricated with silicon gate C2MOS technology. This IC is posed of an independent 2-channel multiplexer with mon SELECT and ENABLE (OE) input. The M74HCT258 is an inverting multiplexer. When the ENABLE input is held "High", outputs of
