SN74LVC16T245ZQLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC16T245ZQLR is a 16-bit dual-supply bus transceiver manufactured by Texas Instruments. It features configurable voltage translation and tri-state outputs, enabling seamless data transfer between buses operating at different voltage levels. The device supports supply voltages ranging from 1.65 V to 5.5 V on both ports A and B. Packaged in a 56-pin Microstar Junior BGA with dimensions of 7 mm x 4.5 mm, it offers bidirectional data flow controlled by a single direction pin. The component operates within a temperature range of -40°C to +85°C and complies with RoHS standards.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable voltage translation allows operation between diverse logic families without external level-shifting circuits.
• Dual-supply architecture supports independent voltage domains for Port A and Port B.
• Tri-state outputs provide high-impedance states to prevent bus contention during inactive periods.

Buffers, Drivers, Receivers, Transceivers Applications

• Mobile applications requiring low-voltage interface translation
• Consumer electronics with mixed-voltage logic systems
• Industrial control systems utilizing dual-supply architectures

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix ZQLR against current manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm end-of-life status or availability through authorized distributors, as this variant may have limited stock compared to standard packages. Ensure compatibility with PCB footprint requirements for the Microstar Junior BGA format before ordering.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between 1.8 V, 2.5 V, or 3.3 V logic domains and 5 V systems. The LVC series offers lower power consumption compared to older AVC variants while maintaining adequate drive strength for most digital buses. Consider the BGA package constraints regarding thermal dissipation and soldering reflow profiles during design integration.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC16T245 family of 16-bit bus transceivers. It shares functional similarities with the SN74AVC16T245 but utilizes Low-Voltage CMOS technology optimized for 1.65 V to 5.5 V operation. The ZQLR suffix specifically denotes the 56-pin Microstar Junior BGA packaging option, distinguishing it from TSSOP or SSOP variants like the DGGR or DLR.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74AVC16T245ZQLR: Offers similar functionality with potentially different speed characteristics and power profiles; verify voltage ranges and timing parameters. SN74LVC16T245DGGR: Pin-compatible alternative in TSSOP-48 package if BGA is not required; check propagation delay differences.
