What are the key features of 74AVC16244DGVRG4?
- AVC family operates from 1.2 V to 3.6 V, enabling direct connection between 1.8 V and 3.3 V logic domains without level-shift ICs
- 16-bit wide unidirectional drive handles full byte-and-byte-wide buses in a single 48-pin TSSOP, reducing chip count on data-bus boards
- 12 mA output sink current at 30 pF load sustains signal integrity at high data rates across PCB traces up to 10 cm
What is 74AVC16244DGVRG4 used for?
The 74AVC16244DGVRG4 is used to buffer and drive 16-bit parallel data buses in processors, FPGAs, and memory interfaces where multiple voltage domains must share a common bus. It is well suited for address and data bus isolation in 1.8 V LPDDR memory controllers, high-speed test and measurement backplanes, and any design requiring low-voltage bus driving with enable-controlled tri-state outputs. The 48-pin TSSOP footprint integrates both bytes of a 16-bit bus in a single component, simplifying PCB layout in space-constrained applications.

Frequently Asked Questions
What supply voltage range does the 74AVC16244DGVRG4 support, and can it interface 1.8 V logic with 3.3 V logic?
The 74AVC16244DGVRG4 operates from 1.2 V to 3.6 V, which directly covers both 1.8 V and 3.3 V logic levels. Because the output high voltage tracks the supply, the device can buffer a 1.8 V LPDDR address bus while its outputs remain compatible with 3.3 V TTL receivers, eliminating the need for separate level-shift ICs on the data path.
How wide is the data path of the 74AVC16244DGVRG4, and how are the output-enable pins organized?
The device provides a 16-bit unidirectional bus path split into two 8-bit banks, each with an independent active-low output-enable pin. This 2×8-bit organization lets designers selectively drive the upper or lower byte of a 16-bit bus independently, which is useful in byte-wide memory expansion schemes where only 8 bits are valid during a cycle.
What is the maximum output sink current of the 74AVC16244DGVRG4, and why does that matter for long PCB traces?
Each output can sink up to 12 mA, which is sufficient to charge and discharge 30 pF PCB trace capacitance at the switching speeds expected in 100 MHz address buses. For longer traces exceeding 5 cm, the 12 mA drive keeps signal edges within the 1 ns rise-time budget, preventing reflections that could corrupt memory read cycles.
When is the 74AVC16244DGVRG4 preferred over the 74LVC16244 for a mixed-voltage PCB design?
The AVC variant is preferred when the supply voltage is below 2.5 V, such as in 1.8 V FPGA I/O banks, because the LVC family requires at least 2.7 V operation. For a Xilinx Zynq or Intel Cyclone V design running I/O banks at 1.8 V, the AVC series maintains valid output levels and 12 mA drive, whereas the LVC variant would be out of its specified supply range.
What package does the 74AVC16244DGVRG4 use and how many pins does it have?
The device is housed in a 48-pin TSSOP (Thin Shrink Small Outline Package) with a 0.5 mm pin pitch, designated JESD-30 code R-PDSO-G48. This package places all 16 I/O lines, 2 enable pins, VCC, and GND in a narrow body roughly 12.5 mm long, making it compact enough for high-density memory-bus routing on a four-layer PCB.
