Frequently Asked Questions
What is the SN74ABTH245DW and what does it do?
The SN74ABTH245DW is an 8-bit bidirectional bus transceiver with 3-state outputs from Texas Instruments. It uses Advanced BiCMOS technology to provide non-inverting data transfer in either direction, controlled by a DIR pin, and features an active-low OE pin to place all outputs in a high-impedance state for bus isolation.
What supply voltage does the SN74ABTH245DW support?
The SN74ABTH245DW operates from a 3.3V supply while maintaining full TTL-compatible input thresholds, making it ideal for mixed 3.3V/5V systems. Its inputs can accept 5V logic signals, enabling seamless voltage translation between different logic families without additional level-shifting components.
What package does the SN74ABTH245DW come in?
The SN74ABTH245DW is housed in a 20-pin SOIC wide-body (DW) package with 7.5mm body width. This surface-mount package provides a compact footprint suitable for high-density PCB designs while offering good thermal performance and ease of automated assembly.
What are the typical applications for the SN74ABTH245DW?
Typical applications include microprocessor address and data bus buffering, memory bus interfaces, backplane bus drivers, and logic level translation between 3.3V and 5V systems. It is also used in industrial control systems, communication equipment, and test instrumentation where reliable bidirectional bus management is required.
How does the SN74ABTH245DW compare to the SN74ABT245?
The SN74ABTH245DW (ABTH series) improves on the standard SN74ABT245 by offering enhanced ESD protection and better latch-up immunity. Both are 8-bit bus transceivers with 3-state outputs, but the ABTH variant is optimized for 3.3V operation while tolerating 5V inputs, making it preferred for modern mixed-voltage board designs.
