SN74LVC125APWRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC125APWRG4 is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage of 1.65V to 3.6V and features independent output-enable inputs for each buffer. The device accepts input voltages up to 5.5V, allowing compatibility with 5V systems while operating at lower voltages. It is housed in a TSSOP-14 package and supports an operating temperature range from -40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features four independent non-inverting buffers with separate output-enable controls
• Provides 3-state outputs that enter high-impedance mode when enabled inputs are high
• Accepts 5.5V input signals while operating on supply voltages as low as 1.65V
• Designed for low power consumption and fast switching speeds

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'G4' indicates compliance with RoHS standards and lead-free manufacturing requirements. Confirm the package type corresponds to the TSSOP-14 variant. Ensure the operating temperature range meets the specific environmental constraints of the target application before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing mixed-voltage logic interfaces requiring translation between 5V and 3.3V or 1.8V domains. The independent OE pins allow precise control over bus contention. Consider the maximum propagation delay specifications relative to the system clock speed to ensure signal integrity across the bus lines.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC125A family of quadruple bus buffer gates. The 'PWR' designation identifies the TSSOP-14 surface-mount package, while the 'G4' suffix denotes Green/RoHS-compliant packaging. It serves as a standard interface solution for buffering digital signals in telecommunications and consumer electronics applications.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle power-up states?

To ensure the high-impedance state during power-up or power-down, the OE input should be tied to VCC through a pull-up resistor.

What is the input voltage tolerance?

Inputs can accept voltages up to 5.5V, allowing the device to function as a translator in mixed 3.3V/5V system environments.
