SN74AHC126D Description

Short technical summary and product information.

The SN74AHC126D from Texas Instruments is a high-speed quadruple bus buffer gate featuring independent line drivers with 3-state outputs. Each output can be disabled when the associated output-enable (OE) input is low, passing data from the A input to the Y output when OE is high.

 

This device operates within a wide voltage range of 2V to 5.5V, making it versatile for various applications. It offers a typical propagation delay of 3.8 ns with a 5V supply, indicating its high-speed capability. The operating temperature range is specified from -40°C to 85°C.

 

The SN74AHC126D is available in a 14-SOIC package, designed for surface mounting. To ensure a high-impedance state during power up or power down, the OE input can be tied to GND through a pull-down resistor. Latch-up performance exceeds 250 mA per JESD 17.

 

This buffer gate is suitable for applications requiring signal buffering and bus interfacing where controlled output states are necessary. Its balanced outputs and over-voltage tolerant inputs contribute to its reliability in system designs.
