SN74LVC1G126DCKR Single Bus Buffer Gate: Schematic, Pinout, and Datasheet

This single buffer is designed to work with a VCC voltage range of 1.65 to 3.6 volts. The SN74LVC1G126DCKR is a single-line driver having three output states. When the output-enable input is low, the output is disabled.

The SN74LVC1G126DCKR gadget performs the Boolean function  Y = A and has a dual buffer gate with output enable control.

This device is completely qualified for Ioff-based partial-power-down applications. When the device is turned off, the Ioff circuitry disables the outputs, preventing dangerous current backflow through the device.

OE should be connected to GND via a pulldown resistor to ensure a high-impedance state during power up or power down; the minimum value of the resistor is specified by the driver's current-sourcing capabilities.

Typical Application

The SN74LVC1G126DCKR Simplified Schematic is shown as follows.

Simplified Schematic

Inputs should not float while working with multiple bit logic devices. Digital logic devices often have functionalities or sections of functions that aren't utilised. When only two of a triple-input  AND gate's inputs are used, for example, or when only three of a four-buffer gate's inputs are used, these are examples. The undefined voltages at the outside connections result in undefined operating states, hence such input pins should not be kept disconnected.

The following diagram illustrates the principles that must be followed at all times. To prevent floating, all unused inputs of digital logic devices must be connected to a high or low bias. The logic level that should be applied to any given unused input is determined by the device's function. They'll usually be connected to GND or VCC, depending on which makes more sense or is handier. Floating outputs are permissible unless the part is a transceiver. If the transceiver has an output enable pin, asserting it will disable the part's outputs section. The input component of the I/Os will not be disabled, therefore they will not float when disabled.
