Overview
The MC74F126D is a quad bus driver belonging to the F/FAST logic series, manufactured by onsemi. It features four independent 1-bit drivers with true outputs and three-state capability. The device operates within a TTL-compatible voltage range and is housed in a 14-pin plastic small outline package (SOIC-14). Key electrical characteristics include a maximum load capacitance of 50 pF and an operating temperature range extending up to 70 °C.
Feature Summary
- Provides four independent one-bit bus drivers for signal routing
- Features three-state output control for bus isolation
- Delivers true output polarity matching input signals
Applications
- High-speed data bus buffering
- Voltage level translation between TTL devices
- Bus-oriented memory and register driving
Procurement Notes
Verify the manufacturer marking against onsemi specifications to ensure authenticity. Confirm the package type matches the required SOIC-14 footprint and pinout. Check the date code and lot traceability if required for your specific manufacturing process. Ensure the component meets the necessary environmental compliance standards for your region.
Selection Notes
Select this component when a quad bus driver with three-state outputs is required for TTL-level applications. Consider the F/FAST series speed characteristics for high-frequency signaling needs. Verify that the 14-pin SOIC package fits the available board space and thermal constraints. Compare power consumption and propagation delays against alternative logic families if performance margins are tight.
Part Context
This part belongs to the broader MC74F12x family of bus drivers, which includes variants like the MC74F125. These components are designed for general-purpose digital logic applications requiring reliable signal transmission and isolation. The F/FAST series is known for its high-speed operation compared to standard logic families, making it suitable for demanding digital systems.
Replacement Considerations
Check for direct cross-references from other manufacturers offering equivalent F/FAST quad bus drivers with three-state outputs in SOIC-14 packages. Verify pin compatibility and electrical parameters before substitution.
