The SN74LVC1G99DCURG4 is a convenient, configurable and multi-function logic device part of the LVC series from Texas Instruments. This device allows flexibility in an application to drive logic from an array of sources. It is used as a single-pole double-throw analog switch and is ideal for use in logic applications where tight timing and electrical noise could be a concern.

The SN74LVC1G99DCURG4 is a multi-function, configurable, and digital logic gate that allows the user to configure it to one of three functions. The device has a single-pole double-throw (SPDT) analog switch and a single-pole single-throw (SPST) open-drain (active-low) output circuit. When voltage is applied to the gate’s terminals, the SPDT switch closes, breaking the connection between the input and the output terminal. Using its active-low open-drain output circuit, the device can sink current from its output terminal to ground, thus activating an external transistor.

The SN74LVC1G99DCURG4 does not contain an internal feedback element, so it can be used to buffer non-inverting logic signals, as well as to provide a logic output with a voltage level as high as ten volts. The device offers excellent noise immunity, low power consumption, and high-speed operation. It is available in two versions: a standard version, with a propagation delay of 12 ns, and a low power version, with a propagation delay of 5 ns.

The SN74LVC1G99DCURG4 is particularly useful in digital logic applications which require fast switching, or in analog applications where tight timing and electrical noise are a concern. It is commonly used in logic gates and logic inverters, as well as in digital or analog-to-digital interface circuits. In all of these applications, the active-low open-drain output circuit is used to provide a logic output, allowing the device to be used to drive other logic devices or transistors, or to provide a pull-down for when the input is at a high logic level.

In summary, the SN74LVC1G99DCURG4 is a multi-function logic device from Texas Instruments’ LVC series. It offers three configurable functions, which include a single-pole double-throw (SPDT) analog switch, as well as an active-low open-drain output circuit. The device is ideal for use in digital logic applications which require fast switching, or in analog applications where tight timing and electrical noise must be controlled. It is also useful for providing a logic output with a higher voltage level than that of the input.
