Overview
The MC74VHCT125AMG is a quad bus buffer with three-state control inputs from onsemi's VHCT logic family. It operates within a supply voltage range of 2.0 V to 5.5 V, ensuring compatibility with standard CMOS and TTL outputs. The device features four independent output enable controls and provides high noise immunity typical of CMOS devices. Packaged in a compact SOEIAJ-14 surface-mount format, it supports low input current and offers robust drive capabilities for memory address drivers, clock drivers, and other bus-oriented systems.
Feature Summary
- Provides four independent non-inverting buffers with three-state control inputs
- Ensures compatibility with standard CMOS and TTL output interfaces
- Delivers high noise immunity suitable for noisy electromagnetic environments
- Features low input current to minimize loading effects on preceding circuits
Applications
- Memory address drivers
- Clock drivers
- Bus-oriented systems
Procurement Notes
Verify the specific package designation SOEIAJ-14 against your PCB footprint requirements. Confirm that the VHCT logic family voltage thresholds align with your system's interface standards. Check for any recent product change notices or end-of-life announcements from onsemi regarding this specific part number before finalizing procurement plans.
Selection Notes
Select this component when interfacing between different logic families requiring CMOS/TTL compatibility. It is suitable for applications needing isolated signal buffering with controlled bus driving. Consider the SOEIAJ-14 package constraints for space-limited designs. Ensure the operating temperature range meets your environmental specifications.
Part Context
This part belongs to onsemi's VHCT logic series, designed for high-speed digital applications. It serves as a direct replacement for legacy LS125 equivalents in terms of pinout and functionality. The VHCT family bridges the gap between HC and HCT logic by offering wide voltage operation with TTL-compatible inputs.
Replacement Considerations
MC74HC125A and MC74HCT125A are functionally similar buffers within the same manufacturer's portfolio. Verify voltage range compatibility, as HC variants may differ in supply voltage specifications compared to the VHCT series.
