Texas Instruments CD74HC238M96

of CD74HC238M96 The CD74HC238 is a high-speed CMOS 3-to-8 line decoder/demultiplexer. The device accepts three binary weighted inputs (A0, A1, A2) and decodes them to activate one of the eight outputs (Y0 to Y7) while all other outputs are deactivated. The device operates with a wide voltage range and offers high-speed operation due to its CMOS technology, making it suitable for various digital applications. Functions - Decoding Capability: Converts a 3-bit binary input into an 8-line output. - Enable Functionality: The outputs can be enabled or disabled via the enable pins (G1, G2A, G2B). - Active Low Outputs: The outputs are active low, meaning the selected output goes low (0) while others remain high (1). Applications - Memory Address Decoding: Used in memory selection and address decoding in microprocessor-based systems. - Data Routing: Suitable for data multiplexing and routing systems in digital circuits. - LED Driving: Can be used to drive multiple LED outputs based on binary inputs. - Instruction Decoding: Often used in various digital applications that require instruction or command decoding. Alternative Parts - 74HC238: A standard version without M96 packaging. - CD74HCT238: Similar functionality but with a TTL-compatible input. - 74LS238: Lower-speed LS series alternative for legacy circuits. - 74HC239: A 2-to-4 line decoder with additional functionalities. Embedded Modules - The CD74HC238M96 can be incorporated in modules as part of larger digital systems where decoding capabilities are required. - It may often be found in programmable logic devices, microcontroller projects, or as part of evaluation kits from Texas Instruments that feature multiple integrated circuits.
