Frequently Asked Questions
What supply voltage does the SN74LVTH244ADBG4 operate at and how does it fit into mixed-voltage systems?
The SN74LVTH244ADBG4 operates at 3.3 V and belongs to the LVT family, which is designed to interface with both 3.3 V and 5 V logic levels, allowing it to translate or buffer signals between TTL-compatible systems running at different supply rails without level-shift circuitry.
What output drive strength does the SN74LVTH244ADBG4 provide?
The device offers a maximum output low current (I_OL) of 64 mA per output, enabling it to sink significant current for driving heavy bus loads or multiple parallel inputs, which is particularly useful in memory address buffering and high-fan-out data bus applications.
How many buffer channels are available and how is output enable controlled on the SN74LVTH244ADBG4?
The SN74LVTH244ADBG4 contains 8 non-inverting buffer channels controlled by active-low output enable pins, placing all outputs in a high-impedance 3-state condition when deasserted, allowing multiple drivers to share a common 8-bit bus safely.
For a compact data-bus PCB design, what package does the SN74LVTH244ADBG4 offer?
The SN74LVTH244ADBG4 is available in a 20-pin SOIC package (R-PDSO-G20) with 1.27 mm lead pitch, making it well suited for automated surface-mount assembly while leaving sufficient land area for decoupling capacitors and routing the 8-bit data bus.
