74ACT253MTCX

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74ACT253MTCX is a dual 4-input multiplexer with 3-STATE outputs housed in a 16-Lead Thin Shrink Small Outline Package (TSSOP). It selects two bits of data from four sources using common select inputs. The device features non-inverting outputs that source and sink 24mA. At VCC = 5.0V, propagation delays range from 5.5ns to 11.0ns for data inputs and 7.0ns to 11.5ns for select inputs. Supply voltage operates between 4.5V and 5.5V.

Signal Switches, Multiplexers, Decoders Feature Summary

• Dual 4-input multiplexing capability with independent output enable controls
• Non-inverting 3-STATE outputs allowing direct bus interfacing
• ACT logic family provides TTL-compatible input thresholds

Signal Switches, Multiplexers, Decoders Applications

• Bus-oriented system data routing
• Data selection circuits requiring high impedance states

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific package variant matches the TSSOP-16 designation. Confirm the ACT logic series requirements align with the 4.5V to 5.5V supply voltage range. Ensure static discharge protection measures are implemented during handling as per standard CMOS procedures.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual independent multiplexing with 3-STATE outputs is required within a compact TSSOP footprint. The ACT series ensures compatibility with TTL logic levels while maintaining CMOS power efficiency. Verify that the 24mA drive current meets the load requirements of the destination circuitry.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the AC/ACT253 family of dual 4-input multiplexers. It serves as a logic implementation of a 2-pole, 4-position switch. The MTC suffix specifically denotes the 16-Lead Thin Shrink Small Outline Package format used for surface mount assembly.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct substitutes include the 74AC253SC and 74ACT253SC variants which share identical logical functionality but utilize different physical packaging formats such as SOIC or SOP.
