Frequently Asked Questions
What is the SN74ABTH245DWRG4 and what logic family does it belong to?
The SN74ABTH245DWRG4 is a non-inverting bidirectional 8-bit bus transceiver from Texas Instruments' ABT (Advanced BiCMOS Technology) logic family. It operates with a 5.5V supply voltage and features common direction control, making it ideal for high-speed data bus buffering and interfacing applications.
What is the output current capability of the SN74ABTH245DWRG4?
The SN74ABTH245DWRG4 provides a maximum low-level output current (IOL) of 64mA, enabling it to drive highly capacitive buses with up to 50pF load capacitance. This high drive strength makes it suitable for backplane interfaces, memory buses, and other demanding digital signal routing applications.
What package does the SN74ABTH245DWRG4 come in and is it lead-free?
The SN74ABTH245DWRG4 is available in a 20-Pin SOIC (Small Outline IC) package with a JEDEC-30 code of R-PDSO-G20. It is RoHS compliant with JEDEC-609 code e4, confirming lead-free construction suitable for environmentally conscious manufacturing processes.
How does the direction control work on the SN74ABTH245DWRG4?
The SN74ABTH245DWRG4 uses a common direction control pin (DIR) that determines the data flow direction for all 8 bits simultaneously. When DIR is high, data flows from the A bus to the B bus; when DIR is low, data flows from B to A. An output enable (OE) pin puts the outputs in a high-impedance state, allowing bus sharing with other devices.
What are typical applications for the SN74ABTH245DWRG4?
The SN74ABTH245DWRG4 is commonly used in microprocessor data bus buffering, memory system interfaces, and bidirectional level translation between logic subsystems. Its high-drive ABT technology makes it well-suited for backplane communication in industrial control systems, telecommunications equipment, and high-speed computing platforms where reliable bidirectional 8-bit data transfer is required.
