Overview
The SN74LS258BML1 is a quad 2-input multiplexer manufactured by onsemi, belonging to the LSTTL logic family. It features four independent multiplexing functions with three-state outputs, allowing data selection from two input lines per function. The device operates within standard TTL voltage levels and is designed for high-speed digital signal routing applications requiring tri-state bus isolation.
Feature Summary
- Provides four independent 2-to-1 multiplexing channels
- Features three-state outputs for bus-driven applications
- Compatible with LSTTL logic standards
Applications
- Digital data routing in computer systems
- Bus interface circuits requiring tri-state control
- Signal selection in instrumentation equipment
Procurement Notes
Verify RoHS compliance status as sources indicate non-compliance. Confirm package type availability and manufacturer lot codes. Ensure compatibility with existing LSTTL design constraints before procurement.
Selection Notes
Select this component for designs requiring quad multiplexing with tri-state output capability. Verify power supply requirements match LSTTL specifications. Consider pinout compatibility if replacing legacy components in existing PCB layouts.
Part Context
Part of onsemi's SN74LS series, this IC serves as a signal selector in digital logic circuits. It complements other LSTTL devices like the SN74LS257B, offering similar functionality with specific packaging variations for surface mount integration.
Replacement Considerations
SN74LS257B offers comparable multiplexing functionality. Verify pin compatibility and electrical characteristics when substituting. Ensure tri-state enable signals align with original circuit design requirements.
