Product Overview: SN74LVC126APWRG4

The SN74LVC126APWRG4 is a high-performance, quadruple bus buffer gate integrated circuit designed by Texas Instruments. This device is part of the LVC family, which is known for its low-voltage operation and compatibility with mixed-voltage system environments. It is particularly suitable for down-translation to 3.3V or 2.5V without the need for external level shifters.

The SN74LVC126APWRG4 features four independent line drivers with 3-state outputs. Each buffer has its own output enable (OE) input, which, when high, disables the output by placing it in a high-impedance state. This allows for the connection of multiple outputs to a common bus without the risk of damaging the device or the bus system.

Constructed with an advanced BiCMOS technology, the SN74LVC126APWRG4 is optimized for low static and dynamic power consumption while maintaining high-speed operation. It can operate over a broad voltage range of 2.7V to 3.6V, making it a versatile choice for interfacing with a wide range of logic levels in modern digital systems.

The device is available in the TSSOP (Thin Shrink Small Outline Package) form factor, under the part number SN74LVC126APWRG4, with the 'G4' suffix indicating the level of RoHS compliance. This package is designed for space-saving on PCBs and is particularly useful in applications where board space is at a premium.

Key features of the SN74LVC126APWRG4 include:

• Support for 5V tolerant inputs, which provides additional interface flexibility.
• High drive capability, with the ability to source or sink up to 24mA at the outputs.
• Low power consumption, with a typical ICC of only 20µA maximum.
• High noise immunity characteristic of LVC logic.
• Operational temperature range from -40°C to +85°C, suitable for industrial applications.

The SN74LVC126APWRG4 is commonly used in a variety of digital applications such as buffer storage, driving buses, and signal gating. Its robust design and advanced features make it an excellent choice for designers looking for reliable and efficient logic level translation and bus-driving capabilities.
