The SN74HC258DR from Texas Instruments is a high-performance, quadruple 2-line to 1-line data selector/multiplexer with 3-state outputs. This integrated circuit is designed to be used in applications where data selection and multiplexing are required. It is part of the HC family, which is well-known for its high-speed CMOS technology.
Key Features
- Wide Operating Voltage Range: The SN74HC258DR operates at a voltage range of 2 V to 6 V, making it suitable for interfacing with both TTL and CMOS logic levels.
- High Current Drive: It can source or sink up to 5.2 mA at the output, providing good drive capabilities.
- Low Power Consumption: The device features a typical low power consumption, with only 20 μA of maximum ICC.
- High Noise Immunity: Characteristic of the HC family, the SN74HC258DR has a high level of noise immunity, which is essential for stable operation in electrically noisy environments.
Functional Description
The SN74HC258DR has four data select inputs (A, B, C, and D), two select inputs (S0 and S1), four outputs (Y0 to Y3), and output enable (OE). The select inputs determine which of the data inputs are routed to the corresponding output. When OE is high, the outputs are in a high-impedance state, allowing for connection to a bus without interfering with other devices.
Applications
This versatile multiplexer is ideal for a wide range of applications, including:
- Data routing
- Signal gating
- Function generation
- Communication systems
- Computer systems
Package and Quality
The SN74HC258DR comes in a small-outline package (SOP) with a Reel of 2500 units, making it suitable for automated assembly processes. It is also available in tape and reel packaging, ensuring safe and secure delivery for bulk orders. Texas Instruments is committed to maintaining high-quality standards, and this product is no exception, adhering to rigorous industry standards for quality and reliability.
