• Logic signal switching.
• Demultiplexing and encoding.
• Multiplexers and decoders.
• Processor logic interfacing.

It can be used in a variety of systems and applications, such as for signal switching, data transfer, timing, synchronization, encoding and decoding, and bus interfacing.

Features

The 74AHC138BQ-Q100X offers the following features:

• Eight 3-state active low outputs.
• Two active low enables.
• 80m ohms total on resistance.
• Olders power consumption.
• Compact CSP package.
• 4.5V to 5.5V operating voltage.

Working Principle

The 74AHC138BQ-Q100X is a logic signal switch, multiplexer and decoder which works by taking the inputs and switching them to outputs based on the state of a logic signal (an enable). The inputs and outputs can be either active-high or active-low. The device is controlled by two active-low enable pins which can be used to control which inputs and outputs are active. The outputs are open-drain which allows them to be daisy-chained together to increase the number of outputs that can be handled.

The 74AHC138BQ-Q100X is an extremely versatile device with a wide range of applications. Its compact size and low power consumption make it ideal for use in digital systems and applications.
