74ACT245MTC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT245MTC is an octal bidirectional transceiver featuring three-state outputs, designed for bus-oriented applications. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a wide operating temperature from -40°C to +85°C. The device provides a propagation delay of 7 ns and delivers high drive currents of 24 mA at both low and high output levels. Packaged in a TSSOP-20 surface-mount format, it accepts TTL input levels while providing CMOS output levels.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal bidirectional data transfer capability with non-inverting logic
• High current drive strength of 24 mA at both A and B ports
• TTL-compatible input thresholds for direct interface with TTL devices
• Three-state outputs allowing effective bus isolation when disabled

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory and instrument control systems
• Data transmission between microprocessors and peripheral devices
• Bidirectional data buffering in industrial communication interfaces

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix MTC confirms the TSSOP-20 package variant. Confirm RoHS compliance status through official documentation as required by project specifications. Check current lifecycle status as distribution availability may vary by region. Ensure ESD handling protocols are followed during assembly due to CMOS sensitivity.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-to-CMOS level translation is required alongside high-speed data transfer. The 7 ns propagation delay suits moderate-speed bus applications. Verify that the 4.5 V to 5.5 V supply range matches the system power architecture. Consider the TSSOP-20 footprint constraints against available PCB real estate.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACT series of logic integrated circuits manufactured by onsemi. It functions as an octal bus transceiver, sharing architectural similarities with other 74xx245 variants but distinguished by its ACT logic family characteristics. The device integrates eight independent bidirectional buffers into a single package for compact system design.
