Product Overview

This 8-bit noninverting bus transceiver uses two separate configurable power-supply rails. The SN74LVC8T245 is optimized to operate with VCCA andVccBsetat1.65Vto5.5V. TheAportis designed to track VccA. VccA accepts any supply voltage from 1.65 V to 5.5 V. The B port is designed to track VccB. VccB accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1 .8-V, 2.5-V, 3.3-V, and 5.5-V voltage nodes.

The SN74LVC8T245 is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR) input and the output-enable (OE) input activate either the B-port outputs or the A-port outputs or place both output ports into the high-impedance mode. The device transmits data from the A bus to the B bus when the B-port outputs are activated, and from the B bus to the A bus when the A-port outputs are activated. The input circuitry on both A and B ports is always active and must have a logic HIGH or LOW level applied to prevent excess lcc and Iccz.

SN74LVC8T245DWR FAQ

How many separate configurable power-supply rails does the SN74LVC8T245 use?

Two.

What is optimized to operate with VCCA andVccBsetat1.65Vto5.5V?

SN74LVC8T245.

Which bus transceiver is designed to track VccA?

TheAportis.

What is bus transceiver?

Bus transceivers are tri-state bi-directional devices which allow the flow of data between two points making them compatible with bus-oriented systems or the bi-directional (input or output) control of interface circuitry. Bus transceivers can be inverting, the TTL 74LS242 or non-inverting, the TTL 74LS243 devices.

What is differential bus transceiver?

The SN65LBC176 differential bus transceiver is a monolithic, integrated circuit designed for bidirectional data communication on multipoint bus-transmission lines. It is designed for balanced transmission lines and meets ANSI Standard RS-485 and ISO 8482:1987(E).
