74ACT245MTCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT245MTCX is an octal bidirectional transceiver belonging to the 74ACT logic series. It features eight non-inverting buffers with three-state outputs housed in a 20-pin TSSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 7 ns. It provides a low-level output current of 24 mA and a high-level output current of -24 mA. The component functions across a temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal bidirectional data transfer capability with common direction control
• Three-state outputs for effective bus line isolation
• High current sinking and sourcing at both A and B ports

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented data transmission systems
• Memory and firmware storage interfaces
• Clock drivers and buffer circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'MTCX' against official datasheets to confirm the tape-and-reel packaging format, as generic part numbers may denote tube packaging. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into surface-mount assembly processes.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 5 V logic family with AC-speed performance is required for octal bus applications. Ensure the design accommodates the 24 mA drive capability and that the system voltage remains strictly within the 4.5 V to 5.5 V operational limits defined for the ACT series.

Buffers, Drivers, Receivers, Transceivers Part Context

This device is part of the broader 74AC/ACT245 family of octal bus transceivers manufactured by onsemi. It shares functional similarities with variants such as the 74AC245MTCX and MM74HCT245MTC, differing primarily in speed characteristics and input/output voltage thresholds associated with their respective logic families.
