Overview
The SN74LS298NS is a Low-Power Schottky (LS) logic integrated circuit manufactured by Texas Instruments. It contains four independent 2-input multiplexers with storage capabilities, housed in a 16-pin Plastic Dual In-line Package (PDIP). The device operates on a supply voltage ranging from 4.75 V to 5.25 V and supports data transfer via serial or parallel-to-serial/parallel counting sequences. It features bipolar logic technology with three-state outputs for effective bus driving.
Feature Summary
- Integrates four independent 2-input multiplexers within a single package
- Includes internal storage registers to maintain selected input states
- Provides three-state outputs to facilitate efficient bus line interfacing
Applications
- Data routing and selection in digital systems
- Parallel-to-serial conversion circuits
- General-purpose logic control applications
Procurement Notes
Verify the specific suffix 'NS' confirms the PDIP-16 plastic package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the design accommodates the standard LS series power requirements and thermal characteristics for reliable operation.
Selection Notes
Select this component when four isolated multiplexer channels with storage are required in a compact form factor. The LS series offers a balance of speed and power consumption suitable for general TTL-compatible designs. Verify that the 16-pin DIP footprint aligns with the target PCB layout constraints.
Part Context
This part belongs to the Texas Instruments 74LS family of logic devices, widely recognized for their compatibility with standard transistor-transistor logic (TTL) systems. The SN74LS298 specifically addresses needs for multi-channel data selection with state retention, serving as a foundational building block for complex digital signal processing architectures.
Replacement Considerations
Direct substitutes include the SN74LS398 and SN74LS399, which offer similar multiplexer functionality. Verify pinout compatibility and electrical specifications before swapping components in existing designs.
