74HC238 SMD IC

Description

The 74HC238 is a versatile integrated circuit (IC) that functions as a 3-to-8 line decoder/de-multiplexer. It's designed to convert a 3-bit binary input into one of eight mutually exclusive outputs. Additionally, it can be used as a de-multiplexer to route data to one of eight output lines based on the input address.

Key Features

• 3-to-8 Line Decoder: Converts 3-bit binary input (A0, A1, A2) to one of eight active-low outputs (Y0-Y7).
• De-multiplexer: Routes data to one of eight output lines based on the input address.
• Three Enable Inputs (E1, E2, E3): Provide flexible control over the decoder/de-multiplexer operation.
• CMOS Technology: Offers low power consumption and high noise immunity.
• Surface Mount Device (SMD): Suitable for space-constrained applications.
• Wide Supply Voltage Range: Operates from 2V to 6V.
