Frequently Asked Questions
What is the output drive current of the SN74LVTH125DE4?
The SN74LVTH125DE4 provides a maximum output low current (I(ol)) of 64mA per output, which is significantly higher than standard logic buffers. This strong drive capability ensures reliable signal integrity when driving heavily loaded bus lines with multiple receivers, long PCB traces, or backplane interconnects in 3.3V digital systems.
How does the 3-state output function on the SN74LVTH125DE4?
Each buffer output on the SN74LVTH125DE4 can be placed into a high-impedance (3-state) condition using an active-low output enable control pin. When disabled, the output is disconnected from the bus, allowing multiple devices to share a single bus without contention. This is essential in bus arbitration, memory banking, and multi-master interface designs.
What logic family does the SN74LVTH125DE4 belong to, and what voltage does it support?
The SN74LVTH125DE4 belongs to the LVT (Low Voltage Technology) / ABT logic family and is designed for 3.3V operation. The LVT family offers fast switching speeds combined with low supply voltage operation, making it compatible with modern 3.3V microprocessors, FPGAs, and ASICs while maintaining compatibility with 5V-tolerant inputs where required.
What package does the SN74LVTH125DE4 use, and is it RoHS compliant?
The SN74LVTH125DE4 is housed in a 14-pin SOIC (Small Outline IC) package (JESD-30 code R-PDSO-G14), a standard SMT package widely available and easy to assemble on PCBs. It is Pb-free with JESD-609 code e4, confirming full RoHS compliance for use in environmentally regulated consumer, industrial, and commercial electronics products.
