Overview
The 74LVC1G125SE-7 is a single non-inverting buffer and bus driver featuring a three-state output, manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.65V to 5.5V and utilizes the LVC logic family. The device provides an output drive capability of ±24mA at 3.3V and includes IOFF circuitry to support partial power-down applications by disabling outputs to prevent damaging current backflow. It is housed in a SOT-353 package with five pins.
Feature Summary
- Features a single-channel non-inverting buffer design with a three-state output that enters a high-impedance state when the output enable pin receives a HIGH-level signal.
- Incorporates IOFF circuitry to disable outputs during partial power-down modes, preventing damaging current backflow when the device is powered down.
- Inputs are tolerant up to 5.5V, allowing direct interface with TTL levels and operation in mixed-voltage environments despite lower supply voltages.
Applications
- Voltage level shifting between different logic domains
- General purpose logic buffering
- Power down signal isolation
Procurement Notes
Verify the specific ordering suffix 'SE' corresponds to the SOT-353 package configuration required for your PCB layout. Confirm RoHS compliance status and lead-free specifications against the latest manufacturer documentation before finalizing procurement orders.
Selection Notes
Select this component for designs requiring a single-channel buffer with active-low output enable control. Ensure the operating voltage falls within the 1.65V to 5.5V range and verify that the SOT-353 footprint matches your assembly constraints.
Part Context
This part belongs to the 74LVC1G125 series of single-buffer gates with three-state outputs. Other variants in the series utilize different package codes such as W5 for SOT25 or Z for SOT553, while maintaining identical logical functionality and electrical characteristics across the product line.
Replacement Considerations
Direct substitutes include other 74LVC1G125 variants from Diodes Incorporated with different package codes (e.g., 74LVC1G125W5-7 for SOT25). Cross-manufacturer equivalents must be verified for pin compatibility and electrical parameter alignment.
FAQ
How does the device handle partial power-down scenarios?
The device includes IOFF circuitry that disables the output to prevent damaging current backflow when the device is powered down.
What is the function of the OE pin?
The Output Enable (OE) pin controls the three-state output; applying a HIGH-level to this pin places the output into a high-impedance state.
