Logic-Buffers, Drivers, Receivers, Transceivers, are digital products that are used to interact with either digital audio signals or digital electrical signals. 74ABT126CSJX is one such device. The following sections detail the application field and working principle of the 74ABT126CSJX.

74ABT126CSJX is a logic product manufactured by Texas Instruments consisting of 4 buffers/drivers. The product has the capability of working in both 3.3V and 5V environment. It provides improved design flexibility by allowing all outputs to be used either as 3-state outputs or as open collector outputs. Because of this, it is suitable to be used in a variety of systems such as ASICs, FPGAs, and CPLDs and is also suitable for use in applications such as printers, scanners, and other USB (Universal Serial Bus) based products.

The 74ABT126CSJX has an integrated Schmitt Trigger. This provides a hysteresis of 0.8V which raises the noise immunity of the device by introducing a delay between the logic low and logic high signals. This improves the operation in noisy environments and increases the number of drivers usable in a single system.

The device is pin-compatible with popular logic products of various vendors. This makes it an ideal choice for use in applications where multiple logic products from different vendors are required.

The 74ABT126CSJX also has a power on reset feature which ensures that the outputs remain in the low state when power is first applied to the device. This guarantees that there is no spurious output activity during power up.

The 74ABT126CSJX works on the principle of using buffers to drive signals onto the outputs. A buffer is basically a circuit element which acts as an isolator or a repeater. They are used to drive high-capacitive loads or to increase the current driving capability of a signal. The inputs to the buffer are the logic-level signals which are then amplified and sent to the outputs through the device. The output signals are at the same logic level as the input signals.

The 74ABT126CSJX is an ideal choice for driving high capacitive loads as it has an output drive capability of 24mA per output. This makes the device ideal for applications where high drive capability is required.

In the 74ABT126CSJX, the outputs can be placed into either of two different modes - open-collector or three-state. The open collector mode allows for connection to a pull-up device such as a resistor and is typically used for bus-oriented designs. The three-state mode allows for each output to be placed into a high-impedance state where it is basically disconnected from the circuit.

In conclusion, the 74ABT126CSJX is a logic product consisting of four buffers/drivers which can be used in a variety of environments including 3.3V and 5V. It has an integrated Schmitt Trigger providing noise immunity and a power-on reset feature to prevent spurious output activity during power up. Its output drive capability of 24mA per output makes it ideal for driving high capacitive loads.
