74ACT125MTCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT125MTCX is a quad buffer with 3-STATE outputs in the ACT logic family. It operates at a supply voltage of 4.5V to 5.5V and features TTL-compatible outputs. The device provides four independent non-inverting buffers in a 14-Lead Thin Shrink Small Outline Package (TSSOP). Key electrical characteristics include an output source/sink current of 24mA, propagation delays up to 10.0ns at 5.0V, and a maximum quiescent supply current of 40.0µA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features TTL-compatible outputs for direct interface with TTL systems
• Outputs capable of sourcing and sinking 24mA

Buffers, Drivers, Receivers, Transceivers Applications

• General-purpose buffering and line driving applications
• Interface between high-speed CMOS logic and TTL-compatible devices
• Data bus buffering in digital communication systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'X' indicates tape and reel packaging as per datasheet specifications. Confirm the ACT logic series designation matches the required 4.5V to 5.5V operating range. Ensure the TSSOP package variant aligns with PCB footprint requirements. Cross-reference manufacturer part numbers to confirm equivalence with legacy Fairchild Semiconductor documentation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-compatible inputs and outputs are required within a 5V system. The ACT series offers performance comparable to AC logic but with TTL input thresholds. Verify that the 24mA drive capability meets load requirements. Consider the 14-TSSOP package dimensions for space-constrained designs requiring surface mount technology.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the 74ACT125 family of quad buffers. It is functionally equivalent to the 74AC125 but includes TTL-compatible input thresholds. The device was originally manufactured by Fairchild Semiconductor and is now covered under onsemi's product portfolio. The 'MTC' designation specifies the 14-lead TSSOP package type.
