74ABT125DB,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ABT125DB,118 is a quad buffer and line driver featuring three-state outputs controlled by active-low output enable inputs (nOE). It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes BiCMOS technology for high-speed performance. The device provides an output capability of -32 mA in the HIGH state and +64 mA in the LOW state. It includes IOFF circuitry to prevent damaging backflow currents during partial power-down applications. The component is housed in a 14-lead SO plastic small outline package (SOT108-1) and supports operation across an ambient temperature range of -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features IOFF circuitry that disables outputs to prevent potentially damaging backflow current when the device is powered down.
• Supports live insertion and extraction through quad bus interface capabilities with specified latch-up protection exceeding 500 mA.
• Provides direct interface compatibility with TTL logic levels while maintaining high-speed BiCMOS performance characteristics.

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down mode operations requiring isolation of powered-off buses
• High-speed data buffering and line driving in digital systems
• Bus interface applications permitting live insertion and extraction

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm the package type and tape-and-reel specifications. Confirm the product status as active or obsolete before finalizing procurement plans. Ensure compliance with RoHS directives and check for any recent packaging updates listed in the revision history.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring robust drive strength with low leakage during power-down states. The BiCMOS process offers superior speed compared to standard CMOS alternatives. Verify that the system voltage remains strictly within the 4.5 V to 5.5 V range to maintain timing specifications and avoid exceeding absolute maximum ratings.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT series of high-performance BiCMOS logic devices manufactured by Nexperia. The 74ABT family is designed for applications demanding faster switching speeds than standard 74HC or 74HCT families while maintaining TTL-compatible input thresholds. The 'D' designation specifically identifies the SO14 surface-mount package variant within this logical family.
