74ABT16245CMTD

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT16245CMTD is a 16-bit bidirectional transceiver with three-state outputs housed in a 48-lead Thin Shrink Small Outline Package (TSSOP). It operates within a supply voltage range of 4.5V to 5.5V and supports an ambient temperature range of -40°C to +85°C. The device features byte-controlled operation with separate control logic for each byte, allowing independent or combined full 16-bit functionality. It provides high drive capability with output sink currents up to 64 mA and source currents up to 32 mA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Byte-controlled architecture enabling independent management of two 8-bit segments or unified 16-bit operation
• High-drive output stage capable of sourcing 32 mA and sinking 64 mA
• Glitch-free bus loading maintained throughout the entire power-up and power-down cycle
• Non-destructive hot insertion capability supported by guaranteed latchup protection

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented data transmission applications
• Memory and memory mapping systems
• Clock drivers and buffering circuits
• Control signal routing in industrial environments

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package integrity and pin alignment against the MTD48 specification. Ensure compliance with RoHS directives and REACH regulations prior to integration. Validate that the specific ordering code matches the required TSSOP variant for thermal and mechanical compatibility.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed bidirectional data transfer is required between buses operating at 5V logic levels. The byte-control feature is essential for systems needing partial bus access without disabling the entire 16-bit path. Consider the 64 mA sink capability for driving heavy capacitive loads or multiple downstream receivers directly.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the ABT logic family, designed for high-speed digital applications requiring robust performance at 5V. It serves as a 16-bit evolution of the 8-bit ABT245 transceiver. The CMTD suffix specifically denotes the 48-lead TSSOP package configuration, distinguishing it from SSOP or other form factors within the same logical family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the SN74ABT16245ADGGR from Texas Instruments. Verify pinout compatibility and electrical characteristics against the original datasheet before substitution. Ensure the replacement part supports the same byte-control functionality and drive current requirements.
