Frequently Asked Questions
What is the direction control feature of the SN74LVTH245ADWR?
The SN74LVTH245ADWR includes a dedicated direction control input (DIR pin) that selects the data flow direction between its A and B ports. This allows the transceiver to be reconfigured in real time to pass data from A to B or B to A, enabling full bidirectional bus buffering in microprocessor and memory interface designs.
What supply voltage does the SN74LVTH245ADWR operate at?
The SN74LVTH245ADWR operates at 3.3V as part of the LVT (Low Voltage Technology) CMOS logic family. Its inputs are also tolerant of 5V logic levels, making it ideal for interfacing between legacy 5V systems and modern 3.3V microcontrollers, FPGAs, and memory devices in mixed-voltage board designs.
What package does the SN74LVTH245ADWR come in?
The SN74LVTH245ADWR is available in a 20-pin SOIC (Small Outline IC) package, identified by JESD-30 code R-PDSO-G20. This standard surface-mount package is compatible with automated assembly processes and is commonly used in industrial, computing, and communications electronics.
What does the 3-state output feature provide in the SN74LVTH245ADWR?
The 3-state output feature allows the SN74LVTH245ADWR outputs to be placed in a high-impedance state via the output enable (OE) pin. This prevents bus contention when the transceiver is not actively driving the bus, enabling multiple transceivers to share a common data bus in multi-master and multi-peripheral system architectures.
What are common applications for the SN74LVTH245ADWR?
Common applications include data bus buffering in microprocessor and DSP systems, memory interface expansion, backplane bus drivers, and multi-card communication boards. The 8-bit bidirectional design with 3-state control is also widely used in industrial automation controllers and embedded systems requiring robust bus signal integrity.
