Frequently Asked Questions

What supply voltage range does the 74ALVCH162835DLG4 support?

The 74ALVCH162835DLG4 operates from a supply voltage of 1.65 V to 3.6 V, making it compatible with both 1.8 V and 3.3 V logic systems. This wide range allows it to interface directly with low-voltage FPGAs and modern microprocessors without level translation.

How many bits does the 74ALVCH162835DLG4 bus driver handle, and what is its output current?

The device is an 18-bit bus driver capable of sinking up to 12 mA per output in its low state. The 3-state outputs allow multiple drivers to share a common bus, with the enable-low control pin used to isolate one driver from the bus when not actively driving.

Which package does the 74ALVCH162835DLG4 use, and is it suitable for dense PCB layouts?

The 74ALVCH162835DLG4 is housed in a 56-pin SSOP (R-PDSO-G56) small-outline package, which provides a compact footprint suitable for high-density PCB layouts. The fine-pitch leads enable placement in space-constrained areas on multi-layer boards used in telecom and server applications.

Can the 74ALVCH162835DLG4 drive 50 pF capacitive loads at high bus speeds?

Yes, the 74ALVCH162835DLG4 is characterized at a load capacitance of 50 pF, a typical value for backplane and multi-drop bus environments. This means it maintains specified propagation delay and output drive integrity when driving moderately loaded PCB traces at ALVCH-family operating speeds.

When should a designer choose the ALVCH family over the ABT or LVC family for bus driving?

The ALVCH family is preferred when the system supply voltage is 1.8 V or 2.5 V, as it is optimized for sub-3.3 V operation with lower switching thresholds than ABT. Compared to LVC, ALVCH offers faster propagation delay and higher output drive current of 12 mA, making it better suited for high-speed 18-bit bus applications with tight timing budgets.
