SN74LVC861ADBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC861ADBR is a 10-bit bus transceiver with 3-state outputs designed for asynchronous communication between data buses. It operates from a supply voltage range of 1.65 V to 3.6 V and features inputs that accept voltages up to 5.5 V, supporting mixed-mode signal operation on all ports. The device allows bidirectional data transmission between the A and B buses based on logic levels at the OEAB and OEBA control inputs. It includes Ioff circuitry to support partial-power-down mode, preventing damaging backflow current when powered down. The maximum propagation delay is 6.4 ns at 3.3 V.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation allowing 5-V input/output voltage with 3.3-V VCC
• Ioff circuitry enables partial-power-down mode by disabling outputs to prevent backflow current
• Inputs accept voltages up to 5.5 V, facilitating translation in mixed 3.3-V/5-V system environments

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication between data buses
• Mixed-mode signal operation in systems combining 3.3-V and 5-V devices
• Partial-power-down applications requiring output isolation during power-off states

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type (SSOP-24) and temperature range (-40°C to +85°C) against your design requirements. Confirm RoHS compliance and lead finish details via the latest TI Package Option Addendum. Ensure ordering suffixes match the desired carrier format and pin configuration before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring 10-bit wide asynchronous data transfer with voltage translation capabilities. It is suitable for mixed-voltage systems where inputs must tolerate 5-V signals while operating at lower supply voltages. Consider the SSOP-24 package constraints and thermal characteristics for PCB layout planning.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments LVC logic family, which provides low-voltage CMOS technology. The SN74LVC861A variant specifically offers 10 channels, distinguishing it from other members like the SN74LVC245 or SN74LVC4245 which provide 8 channels. It shares functional similarities with the SN74LVC863 but differs in bit width.
