What are the key features of 74ALVCH16501DLRG4?
- Independent output enable for each direction provides fine-grained bus control without additional logic
- ALVCH-family low-voltage design supports 2.3 V to 3.6 V supply with 5 V-tolerant inputs for mixed-voltage systems
- 18-bit wide data path in a 56-pin SSOP package minimizes board footprint while maximizing bus bandwidth
What is 74ALVCH16501DLRG4 used for?
The 74ALVCH16501DLRG4 is widely used in high-speed backplane and memory bus designs where bidirectional 18-bit data transfer between different voltage domains is required. It fits FPGA I/O expansion, DSP memory interfaces, and multi-board systems where registered bus transceivers manage signal integrity at 3.3 V logic levels. Its independent per-direction enables make it suitable for bus arbitration and split-bus architectures in network and communications equipment.

Frequently Asked Questions
What supply voltage range does the 74ALVCH16501DLRG4 support, and what load capacitance is specified?
The 74ALVCH16501DLRG4 operates from a 2.3 V to 3.6 V supply and is characterized at 50 pF load capacitance, ensuring reliable signal integrity on high-speed backplane and memory bus applications with mixed-voltage inputs up to 5 V.
How wide is the data path and how many pins does the SSOP package expose?
The device provides an 18-bit bidirectional data path housed in a 56-pin SSOP package, delivering a wide bus in a compact footprint suitable for memory controller, FPGA expansion, and multi-processor bus interface designs.
When would independent output enables per direction be preferred over a single shared output enable?
Independent per-direction enables let designers hold one bus side in high-impedance while the other drives, enabling half-duplex protocols, bus arbitration schemes, and split-bus topologies without additional discrete gates, saving at least 1 extra logic IC per bus segment.
Is the 74ALVCH16501DLRG4 suitable as an alternative to 74ABT16501 devices in 3.3 V systems?
Yes. The ALVCH family offers comparable 18-bit registered transceiver functionality to the ABT family but at lower 2.3 V to 3.6 V supply voltages, making it a drop-in upgrade for power-sensitive designs that need to reduce I/O supply from 5 V to 3.3 V.
