The SN74LVC126APWRE4 is a member of the Texas Instruments LVC family of logic devices. This product line includes buffers, drivers, receivers, and transceivers that feature low-voltage operation, allowing designs to be optimized for smaller board space and lower power consumption. The SN74LVC126APWRE4 is an advanced version of the basic SN74LVC126APWR, with the addition of an enhanced output drive. The SN74LVC126APWRE4 is an integrated 3-state buffer with selectable common-mode range, designed to serve as a connection between two buses.

Application Field

The SN74LVC126APWRE4 is suitable for applications where logic signals need to be routed from one board or system to another with minimal noise or distortion. Its low-voltage operation ensures compatibility with upstream and downstream logic gates, while its enhanced output drive ensures reliable logic operations. This buffer can also be used in a variety of applications where the output can take on three states: high, low, and high impedance, and is particularly suitable for conditions in which a smaller board space, a high-capacitance bus, and high driving capability are required.

Working Principle

The SN74LVC126APWRE4 three-state buffer contains eight noninverted 3-state outputs which use CMOS technology. It is designed with two enable pins (E1 and E2): when E1 or E2 is HIGH, the corresponding nibble (bits 0-3 or 4-7) is enabled; when both E1 and E2 are LOW, the corresponding nibbles are disabled, putting the selected outputs in a high-impedance state. The output signals from the buffer are in three states: high, low, or high-impedance. The HSI/LSI (High-Z to Low-Z Select Input) pin is used to select the output drive performance. When HSI is LOW, the outputs will assume a weak drive condition, driving standard load capacitances; when HSI is HIGH, the outputs will assume a strong drive condition, driving heavy load capacitances.

The SN74LVC126APWRE4 also has an input clock synchronization feature which allows the outputs to switch simultaneously when both E1 and E2 are LOW, preventing signal skew between output signals. In addition, it has an open-drain output signal, which allows different output states to be pulled up to the power supply voltage. This feature is particularly useful in a variety of signal conversion applications.

The SN74LVC126APWRE4 is an excellent choice for applications that require smaller board space, low-voltage operation, high-capacitance loads, and high output-driving capability. Its multiple features make it an ideal choice for applications such as signal routing, signal translation, and bus-isolation.
