The UPD74HC153C is a high-speed CMOS dual 4-input multiplexer manufactured by NEC (now Renesas Electronics). This device selects one of four data inputs from each of two channels based on a common select input. It is commonly used in digital logic circuits for data routing, selection, and control applications.
Applications:
- Data Selection: Selects one of multiple data sources for processing or transmission.
- Address Decoding: Decodes memory addresses to select specific memory locations.
- Logic Function Generation: Implements custom logic functions by selecting different input combinations.
- Digital Switching: Switches between different signal sources in audio or video systems.
Features:
- Dual 4-Input Multiplexer: Provides two independent 4-input multiplexer channels.
- High Speed Operation: Offers fast signal propagation for high-frequency applications.
- Low Power Consumption: Minimizes energy usage in battery-powered devices.
- Wide Operating Voltage Range: Operates with a supply voltage from 2V to 6V.
- High Noise Immunity: Provides reliable operation in noisy environments.
- CMOS Technology: Offers low static power dissipation.
Benefits:
- Flexible Data Selection: Allows for selection of one of four data sources in each channel.
- Improved System Performance: Enables faster data processing and signal routing.
- Extended Battery Life: Reduces power consumption in portable devices.
- Reliable Operation: Provides stable performance in noisy environments.
- Simplified Circuit Design: Reduces the number of components required for data selection.
Additional Details:
The UPD74HC153C features separate enable inputs for each channel, allowing for independent control of the multiplexer functions. The device is typically available in a DIP (Dual In-Line Package) or SOIC (Small Outline Integrated Circuit) package. NEC provides detailed datasheets and application notes to assist in the proper use of this multiplexer. The input and output pins are protected against electrostatic discharge (ESD). It complies with JEDEC standards. The operating temperature range is typically from -40°C to +85°C.
