SN74LVC861APWT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC861APWT 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 bus and B bus based on logic levels at the OEAB and OEBA control inputs. It includes Ioff circuitry for partial-power-down mode and latch-up performance exceeding 250 mA per JESD 17. The maximum propagation delay is 6.4 ns at 3.3 V.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'T' corresponds to the TVSOP (DGV) package configuration when sourcing this component. Confirm RoHS compliance status and lead finish details against the latest manufacturer documentation prior to procurement. Ensure the selected variant matches the required thermal impedance and operating temperature range specifications for the intended application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring bidirectional 10-bit data transfer between buses operating within the 1.65 V to 3.6 V range. It is suitable for applications needing voltage translation capabilities where inputs can tolerate up to 5.5 V while the core operates at lower voltages. Consider the TVSOP package dimensions and pin count for PCB layout constraints.
