74LVT125DB,112

Overview

The Nexperia 74LVT125DB,112 is a quad buffer and line driver featuring 3-state outputs controlled by active LOW enable inputs. It operates within a supply voltage range of 2.7 V to 3.6 V and utilizes BiCMOS technology for high-speed performance and robust output drive capabilities. The device includes bus hold data inputs to eliminate the need for external pull-up resistors on unused lines. It supports partial power-down applications through IOFF circuitry, which prevents damaging backflow currents when the device is powered down.

Feature Summary

• Quad bus interface with 3-state buffers
• Bus hold data inputs eliminate need for external pull-up resistors
• IOFF circuitry provides partial Power-down mode operation
• Live insertion and extraction permitted

Applications

• Parallel communications
• Clock distribution
• Buffering memory buses

Procurement Notes

Verify the specific ordering suffix '112' against the manufacturer's current production status, as legacy variants may have been superseded or discontinued. Confirm that the SO14 package type matches the design requirements. Ensure compliance with JEDEC standards JESD8C and ESD protection ratings relevant to the target application environment before finalizing procurement.

Selection Notes

Select this component for designs requiring a 3.3 V logic level buffer with high noise immunity and direct TTL interface capability. The wide input voltage tolerance up to 5.5 V allows compatibility with mixed-voltage systems. Consider the SO14 package dimensions for PCB layout constraints and verify thermal dissipation needs based on the specified output current capabilities under recommended operating conditions.

Part Context

This part belongs to the 74LVT logic family, designed for low-voltage (3.3 V) applications. It serves as a non-inverting buffer/line driver. The 'DB' designation indicates the SO14 plastic small outline package variant. It is functionally compatible with other 74LVT series devices but offers specific pinout and electrical characteristics defined by the 74LVT125 architecture.

Replacement Considerations

Check for updated package versions such as TSSOP14 (PW) or DHVQFN14 (BQ) if space constraints differ. Verify functional equivalence with other 74LVT125 variants from different manufacturers, ensuring matching voltage ranges and 3-state control logic.
