74ACT258MTCX

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74ACT258MTCX is a quad 2-input multiplexer with 3-STATE outputs housed in a 16-lead TSSOP package. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature from -40°C to +85°C. The device features TTL-compatible inputs and provides inverted data outputs capable of sourcing or sinking 24mA. Propagation delays are specified at 9.5ns maximum for input-to-output transitions and 11.5ns maximum for select-to-output transitions under standard conditions.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides four independent 2-input multiplexing channels controlled by a common select line
• Features 3-STATE outputs that switch to high impedance when the output enable input is HIGH
• Outputs present selected data in inverted form for direct bus-oriented system interfacing
• Includes design capabilities for multiplexer expansion by tying compatible outputs together

Signal Switches, Multiplexers, Decoders Applications

• Bus-oriented systems requiring signal selection between two sources
• Digital logic circuits utilizing 4-pole, 2-position switching functions
• Multiplexer expansion configurations where multiple units are interconnected

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify component authenticity through official manufacturer documentation and authorized distribution channels. Confirm the specific MTC16 package variant matches your PCB footprint requirements. Ensure compliance with RoHS directives if applicable to your manufacturing standards. Review absolute maximum ratings to prevent damage during handling and assembly processes.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a quad 2-input multiplexer with active-low output enable is required. The ACT series offers reduced power consumption compared to older technologies while maintaining TTL compatibility. Verify that the 3-STATE output capability aligns with your bus architecture needs. Consider the 16-lead TSSOP package dimensions for space-constrained designs.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the 74ACT family of high-speed CMOS logic devices originally developed by Fairchild Semiconductor. The ACT series combines the speed of bipolar logic with the low power consumption of CMOS technology. The 74ACT258 specifically implements a quad multiplexer function with tri-state control, serving as a critical interface component in digital data routing applications.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check for equivalent parts such as the 74ACT258SC (SOIC) or 74ACT258SJ (SOP) if different packaging is needed. Verify pinout compatibility before substituting with other quad multiplexer variants. Ensure replacement components maintain the same 3-STATE output characteristics and voltage specifications.
