SN74LVC861ADWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC861ADWR is a 10-bit bus transceiver with 3-state outputs manufactured by Texas Instruments. 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 asynchronous data transmission between the A and B buses depending on logic levels at the OEAB and OEBA control inputs. Maximum propagation delay is 6.4 ns at 3.3 V. It includes Ioff circuitry for partial-power-down mode and latch-up performance exceeding 250 mA per JESD 17.

• Partial-power-down applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type (DW, DB, PW, DGV) required for your design as the SN74LVC861A family offers multiple options. Confirm RoHS compliance and lead finish details via the manufacturer's ordering information. Ensure the selected variant matches your thermal and mechanical constraints before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing 10-bit buses requiring 3-state isolation in low-voltage systems. It is suitable for designs needing mixed-voltage compatibility between 3.3-V and 5-V domains. Consider the specific package dimensions and pinout if space is constrained, as multiple package styles are available within the same logical function.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC861A series of 10-bit bus transceivers. It is designed for low-voltage CMOS technology, offering high speed and low power consumption. The device is widely used in embedded systems where bidirectional data transfer between different voltage domains is necessary.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct substitutes like SN74LVC861ADW or SN74LVC861APWR which share the same logical function but differ in packaging. Ensure any replacement maintains the 1.65 V to 3.6 V operating range and 5.5 V input tolerance.
