MC74AC245MELG

Overview

The MC74AC245MELG is an octal bidirectional transceiver with three-state inputs and outputs, belonging to the onsemi 74AC logic family. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40°C to +85°C. The device provides a propagation delay of up to 8.5 ns at 5.0 V and features a maximum quiescent supply current of 80.0 µA. It delivers a source/sink output current capability of 24 mA at both A and B ports.

Feature Summary

• Bidirectional data path controlled by Transmit/Receive input
• Three-state outputs for bus-oriented applications
• High current sinking and sourcing capability

Applications

• Bus-oriented systems requiring bidirectional data transfer
• Memory and memory interface control
• Clock drivers and buffered oscillators

Procurement Notes

Verify that the specific part number suffix matches the required package type and lead finish. Confirm RoHS compliance status and moisture sensitivity level requirements against the project specifications before finalizing procurement orders.

Selection Notes

Select this component when high-speed bidirectional data transfer is required across multiple lines. Ensure the system voltage falls within the 2.0 V to 6.0 V operating range and that the thermal environment remains within the specified -40°C to +85°C limits.

Part Context

This device is part of the MC74AC245 series, which includes variants like the MC74AC245DWG and MC74AC245DTG. These components share identical electrical characteristics but differ in physical packaging, such as SOIC-20 or TSSOP-20 configurations.

Replacement Considerations

Compatible substitutes include MC74AC245DWG and MC74AC245DTG. Verify pin compatibility and package dimensions before substitution.
