Frequently Asked Questions
What is the operating voltage range of the SN74LVTH125D?
The SN74LVTH125D operates from 2.7V to 3.6V supply voltage, making it fully compatible with standard 3.3V digital systems. It is part of Texas Instruments' LVT (Low-Voltage Technology) family designed for low-power, high-speed 3.3V logic applications.
How does the 3-state output enable work on the SN74LVTH125D?
Each of the four buffers in the SN74LVTH125D has an independent active-low output enable (OE) pin. When OE is LOW, the corresponding output is enabled and drives the output signal. When OE is HIGH, the output enters a high-impedance (3-state) condition, effectively disconnecting it from the bus and allowing multiple devices to share the same data lines.
What are common applications for the SN74LVTH125D?
The SN74LVTH125D is commonly used for bus buffering and line driving in microprocessor systems, FPGA I/O expansion, memory interface circuits, and mixed-voltage board designs requiring 5V-to-3.3V level translation. Its 64mA IOL and 50pF load capacitance rating make it suitable for driving moderate-length PCB traces in industrial and communication equipment.
What package does the SN74LVTH125D come in and what is the pin count?
The SN74LVTH125D is available in a 14-pin SOIC (Small Outline Integrated Circuit) package, designated as R-PDSO-G14 per JESD-30. This surface-mount package is RoHS-compliant (Pb-free, JESD-609 code e4) and is well suited for automated SMT assembly in space-constrained PCB designs.
Is the SN74LVTH125D compatible with 5V TTL logic inputs?
Yes, the SN74LVTH125D inputs are TTL-compatible, allowing it to accept 5V TTL logic signals while operating from a 3.3V supply. This makes it a practical choice for interfacing legacy 5V logic devices with modern 3.3V systems without requiring additional level-shifting circuitry.
