Overview
The MC74ACT125N is a quad 3-state buffer manufactured by onsemi, utilizing high-performance silicon-gate CMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs. The device provides four non-inverting channels with low-enable control, capable of sourcing and sinking up to 24 mA per output. It is available in SOIC-14 and TSSOP-14 packages, designed for surface-mount applications across an operating temperature range of -40°C to +85°C.
Feature Summary
- Features TTL-compatible inputs for direct interfacing with standard logic families
- Provides three-state outputs controlled by a low-active enable signal
- Capable of driving loads with high current sourcing and sinking capabilities
Applications
- High-speed data bus buffering
- Clock distribution networks
- Memory address/data drivers
Procurement Notes
Verify the specific package suffix (D for SOIC or N for DIP) against the datasheet ordering information. Confirm RoHS compliance status and check for lead-free markings. Ensure the selected variant matches the required thermal resistance and moisture sensitivity level for the intended assembly process.
Selection Notes
Select this component when TTL-level input compatibility is required alongside CMOS drive strength. Compare propagation delay specifications at 5.0 V against system timing requirements. Evaluate package options based on PCB space constraints and thermal dissipation needs relative to the application environment.
Part Context
This part belongs to the MC74AC/ACT125 family of quad buffers. It shares functional similarities with the MC74AC125 but distinguishes itself through ACT-specific input thresholds that align with TTL standards. The family supports various packaging styles including SOIC and TSSOP for flexible integration.

FAQ
What is the input threshold characteristic of the MC74ACT125?
The MC74ACT125 features TTL-compatible input thresholds, allowing it to interface directly with TTL logic levels while maintaining CMOS performance characteristics.
How does the enable function operate?
The device utilizes a low-active enable input. When the enable pin is low, the outputs are active and follow the input states. When the enable pin is high, the outputs enter a high-impedance state.
