Frequently Asked Questions
What is the output drive current of the SN74LVTH244ADBE4?
The SN74LVTH244ADBE4 provides a maximum low-level output current (IOL) of 64mA, making it capable of driving heavy bus loads. The high output drive strength is well-suited for address and data buses in embedded systems operating at 3.3V.
Is the SN74LVTH244ADBE4 compatible with 5V logic signals?
Yes, the SN74LVTH244ADBE4 belongs to Texas Instruments' LVT (Low-Voltage Technology) family, which features 5V-tolerant inputs. This allows the device to be used in mixed-voltage environments where 5V legacy logic must interface with 3.3V systems without additional level-shifting components.
What package does the SN74LVTH244ADBE4 use and what does 'DBE4' mean?
The SN74LVTH244ADBE4 comes in a 20-pin SOIC (Small Outline IC) package, identified by JESD-30 code R-PDSO-G20. The 'D' suffix denotes the SOIC package, 'B' indicates a specific body width variant, and 'E4' refers to Pb-free (lead-free), RoHS-compliant material with JESD-609 code e4.
What are the typical applications for the SN74LVTH244ADBE4?
This octal buffer/driver is commonly used for address bus buffering, data line driving, FPGA I/O expansion, and memory interface designs. Its 3-state outputs and active-low enable pin make it ideal for shared bus architectures in microprocessor systems, industrial controllers, and communications equipment.
