Overview
Description
The SN74LVC8T245DBR is an 8-bit non-inverting bus transceiver from Texas Instruments, featuring bidirectional voltage-level translation and designed for asynchronous communication between data buses. It operates with two separate power-supply rails, allowing for translation between 1.4 V to 3.6 V on the A-port and 1.4 V to 5.5 V on the B-port, making it ideal for interfacing between mixed voltage systems. The device is part of the LVC (Low Voltage CMOS) family, providing low power consumption and high-speed operation.
Key features include direction control, a 3-state output for bus-oriented applications, and the ability to withstand higher-voltages with its Ioff circuitry, preventing backflow current when the device is powered down. The SN74LVC8T245DBR is packaged in a small-outline integrated circuit (SOIC) and is suited for various applications, such as portable electronics, computing, and networking. Its robust design and flexibility in voltage translation make it a versatile choice for designers needing reliable data transfer between different logic levels.

Pinout
The SN74LVC8T245DBR is a dual-supply bus transceiver from Texas Instruments, designed for asynchronous communication between two buses. It has 20 pins and operates with dual supply voltages, allowing voltage level translation between 1.4 V to 3.6 V on the A side and 1.4 V to 5.5 V on the B side.
Key functions include:
- Bidirectional Data Transfer: It allows for data transmission in both directions between buses A and B. The direction is controlled by the DIR pin.
- Output Enable: The OE pin is used to enable or disable the outputs, placing them in a high-impedance state when disabled.
- Level Shifting: It provides voltage level translation between the two buses.
The typical pin configuration includes power supply pins (VCCA and VCCB), ground pins (GND), input/output pins for the A and B buses, and control pins (DIR and OE). This makes it suitable for applications where voltage translation and bidirectional data flow are needed.
