74LVC125AS14-13

Overview

The 74LVC125AS14-13 is a quadruple 3-state buffer manufactured by Diodes Incorporated in the SO-14 package. It operates within a supply voltage range of 1.65V to 5.5V and features inputs tolerant to 5.5V for mixed-voltage environments. The device sinks 24mA at VCC = 3.3V and includes I_OFF circuitry to prevent damaging backflow during partial power-down applications. It supports CMOS low power consumption and provides ESD protection exceeding JESD 22 standards.

Feature Summary

• Provides four independent buffers with three-state outputs controlled by associated output enable pins.
• Supports partial-power-down mode operation via IOFF circuitry to disable outputs and prevent current backflow.
• Inputs accept up to 5.5V, allowing compatibility with 3.3V or 5.5V driven signals for voltage translation.

Applications

• Voltage level shifting
• General-purpose logic
• Power down signal isolation

Procurement Notes

Verify the specific ordering suffix 'S14' confirms the SO-14 surface-mount package type required for your PCB layout. Confirm that the '-13' suffix corresponds to the tape and reel packing quantity of 2,500 units as specified in the manufacturer's ordering information. Ensure compliance with RoHS 3 and lead-free requirements if applicable to your assembly process.

Selection Notes

Select this component when designing circuits requiring four non-inverting buffers with high drive capability in a compact SO-14 footprint. It is suitable for systems operating between 1.65V and 5.5V where input tolerance to 5.5V is necessary. Consider the I_OFF feature if the design requires safe isolation during power-down states to protect downstream components from backflow currents.

Part Context

This part belongs to the 74LVC125A family of quadruple 3-state buffers produced by Diodes Incorporated. The 'S14' designation specifically identifies the SO-14 package variant, distinguishing it from the TSSOP-14 option. It is part of the broader LVC logic series designed for low-voltage applications with extended voltage tolerance capabilities.

Replacement Considerations

The datasheet lists the 74LVC125AT14-13 as an alternative package option (TSSOP-14) within the same product family. No other cross-manufacturer substitutes are explicitly confirmed in the provided documentation.

FAQ

How does the device handle partial power-down scenarios?

The device incorporates IOFF circuitry that disables the output when powered down, preventing damaging current backflow into the system.

What is the maximum input voltage tolerance?

The inputs are tolerant to 5.5V, allowing them to be driven by 3.3V or 5.5V signals even if the device VCC is lower.
