What are the key features of SN74HC652DWG4?
- Bidirectional registered bus transceiver with independent output enable control for each data direction
- Operates across 2V to 6V VCC supply range supporting mixed-voltage system interfacing at 150 pF load capacitance
- HC/UH family guarantees 6 mA output sink current with high noise immunity for reliable data bus communication
What is SN74HC652DWG4 used for?
The SN74HC652DWG4 is well-suited for microprocessor data bus buffering and memory interface applications where bidirectional data flow between two 8-bit buses requires register latching. It excels in industrial control systems, communication backplanes, and embedded systems that need independent direction control and registered outputs to prevent bus contention. The device is also ideal for level-shifting applications between 3.3V and 5V logic domains in mixed-voltage PCB designs.

Frequently Asked Questions
How does the SN74HC652DWG4's independent output enable per direction improve bus control compared to single-enable transceivers?
The SN74HC652DWG4 provides separate output enable signals for each of its two 8-bit data directions, allowing one direction to drive the bus while the other remains tri-stated. This eliminates bus contention in bidirectional systems, making it superior to single-enable transceivers in multi-master microcontroller designs. With a 6 mA sink current per output and 150 pF load capacitance support, the device ensures clean signal transitions in noisy industrial environments.
Which supply voltage range does the SN74HC652DWG4 support, and how does this affect compatibility with 3.3V and 5V logic systems?
The SN74HC652DWG4 operates from 2 V to 6 V VCC, making it compatible with both 3.3 V and 5 V logic systems without additional level-shifting circuitry. At 5V supply, the device delivers 6 mA output current with propagation delays under 10 ns, while at 3.3V it still meets HC family thresholds for reliable logic level translation. This dual-voltage compatibility reduces BOM cost in mixed-logic embedded systems.
For a 24-node industrial communication backplane, what board area does the 24-SOIC package of the SN74HC652DWG4 require?
The SN74HC652DWG4 in a 24-pin SOIC package occupies approximately 154 mm² of board area with a body footprint of 15.4 mm × 7.5 mm and 1.27 mm pin pitch, making it compact enough to fit 4 devices per 100 mm × 100 mm PCB zone. For high-density backplane designs handling 8-bit bidirectional data buses, this package size enables efficient layout with 100 mil trace routing on standard FR4. The SOIC package also offers better thermal dissipation than SSOP alternatives at the same lead count.
