74LVT126PW,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74LVT126PW,118 is a quad buffer and line driver featuring three-state outputs controlled by dedicated output enable inputs. It operates within a supply voltage range of 2.7 V to 3.6 V and accepts overvoltage tolerant inputs up to 5.5 V. The device utilizes BiCMOS technology for high-speed performance and provides an output capability of +64 mA and -32 mA. It includes bus-hold data inputs to eliminate external pull-up resistors and features IOFF circuitry for partial power-down applications. The component is specified for operation from -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Quad bus interface with three-state buffers
• Overvoltage tolerant inputs compatible with 5 V systems
• Bus-hold data inputs eliminate need for external pull-ups
• IOFF circuitry prevents damaging backflow current during power-down

Buffers, Drivers, Receivers, Transceivers Applications

• Driving bus lines in mixed voltage environments
• Live insertion and extraction permitted interfaces
• Partial power-down mode operations

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm that the application environment remains within the recommended operating conditions for supply voltage and ambient temperature. Ensure input signals do not exceed the absolute maximum ratings to prevent permanent damage. Check for compliance with relevant JEDEC standards if required by the design specification.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad buffer with three-state control is required for 3.3 V logic systems interfacing with 5 V buses. The BiCMOS technology offers high speed and strong output drive capabilities suitable for bus lines. Consider the TSSOP14 package for space-constrained designs requiring surface mount assembly. Verify compatibility with TTL input levels if direct interface is necessary.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74LVT series of low-voltage TTL-compatible logic devices. It serves as a high-performance BiCMOS product designed specifically for VCC operation at 3.3 V.
