The IC component SN74HCS138PWR is a 3-to-8 line decoder/demultiplexer integrated circuit, manufactured by Texas Instruments. It is designed to decode three binary inputs (A, B, and C) into eight mutually exclusive outputs. Here is an overview and key features of this IC component:
1. Decoder Functionality: SN74HCS138PWR has an active low enable (G) input, which when set to logic low, enables the decoding operation. It decodes the three binary inputs A, B, and C into eight outputs (Y0 to Y7) based on the selected input combination.
2. Binary to Octal Conversion: The IC performs a binary to octal conversion, where one of the eight outputs is active based on the binary input combination. For example, if A=0, B=0, and C=0, then the Y0 output will be active. This way, it enables the selection of a specific output based on the binary inputs.
3. Enable Input Options: In addition to the three binary inputs, SN74HCS138PWR provides three enable inputs, G1, G2A, and G2B. These enable inputs allow cascading multiple ICs together to create a larger decoder network. The enable inputs act as additional selection criteria for the decoding process
