Signal Switches, Multiplexers, Decoders Harris Corporation CD74HC257E Overview
The CD74HC257E from Harris Corporation is an integral component for digital systems requiring reliable multiplexing functionalities. This quad 2-input multiplexer combines high-speed performance with low-power consumption, housed in a practical 16-pin DIP (Dual In-line Package). The device is designed to effectively handle multiple digital signals, allowing for the selection of one out of two inputs for each output, guided by a common select input. This capability makes the CD74HC257E a versatile choice for sophisticated yet demanding digital environments. The use of advanced silicon-gate CMOS technology enhances its operational reliability and ensures compatibility across a wide range of voltage levels, making it a robust choice for critical digital applications.
CD74HC257E Features
- Four independent 2-to-1 multiplexers
- Standard 16-pin DIP format for easy integration
- Wide operating voltage range of 2V to 6V
- Low power consumption and high noise immunity typical of CMOS devices
- Non-inverting outputs which retain the integrity of the input signal
CD74HC257E Applications
- Data Routing: Ideal for routing digital data streams in communication equipment, where precise and reliable switching between data sources is necessary.
- Signal Gating: Useful in digital signal processing systems where multiple signals need to be managed and directed to different parts of the system without interference.
- Function Generation: Used in function generators where different functions are selected and outputted based on the mode of operation.
- Computer Peripheral Switching: Effective in managing inputs and outputs within computer peripherals, enhancing functionality and efficiency.
- Audio/Video Equipment: Can be utilized in A/V systems for signal selection, helping in the integration and management of audio and video signals.
