Overview
The MC10EL58DTG is a 2:1 multiplexer from onsemi, functionally equivalent to the E158 device but offering significantly faster propagation delays and output transition times. It operates in PECL mode with VCC ranging from 4.2 V to 5.7 V (VEE = 0 V) or NECL mode with VEE ranging from -4.2 V to -5.7 V (VCC = 0 V). The device features internal input pulldown resistors on data and select inputs, ensuring stable logic levels. It supports a maximum toggle frequency of 1.5 GHz and includes temperature compensation characteristics within its AC performance metrics.
Feature Summary
- High-speed signal selection with propagation delays as low as 230 ps for rapid response in demanding applications.
- Integrated internal pulldown resistors on all inputs to simplify circuit design and enhance signal stability.
- Dual-mode operation capability supporting both PECL and NECL power supply configurations for flexible system integration.
Applications
- High-frequency communication systems requiring precise signal routing
- Fast data acquisition networks needing minimal latency
- Complex digital logic circuits utilizing ECL family standards
Procurement Notes
Verify the specific package suffix DTG corresponds to the TSSOP-8 form factor required for your PCB layout. Confirm that the ordering information matches current availability status, as some variants may be discontinued. Ensure environmental compliance requirements align with Pb-Free and Halogen-Free specifications before finalizing procurement orders.
Selection Notes
Select this component when ultimate AC performance is critical compared to standard E158 equivalents. Consider the TSSOP-8 package constraints if space is limited. Evaluate thermal resistance values against your board's airflow conditions to ensure junction temperatures remain within safe operating limits during continuous high-frequency toggling operations.
Part Context
This device belongs to the MC10EL/100EL series of high-performance ECL logic components. It serves as an advanced replacement for legacy E158 multiplexers, providing improved switching speeds while maintaining functional compatibility. The series is designed for applications where signal integrity and timing precision are paramount over cost considerations.
Replacement Considerations
Direct substitutes include the MC100EL58DTG, which offers similar functionality with enhanced temperature compensation features. Verify pinout compatibility and electrical parameter overlaps before swapping devices in existing designs to ensure seamless integration without circuit modification.
FAQ
What happens if the SEL input is left open?
The device features internal input pulldown resistors, causing the SEL pin to default to a low state if left unconnected.
Does this device support LVDS interfaces directly?
No, it is an ECL device. Interfacing with LVDS requires additional translation circuitry as specified in relevant application notes.
