SN74LVTH573GQNR is a logic latch integrated circuit (IC) designed for use in portable, automotive, and industrial applications. It is a 3-state octal latch with 3-state outputs. The outputs from the latch are enabled and disabled by a common, active low enable input.The SN74LVTH573GQNR is a versatile, low power and low voltage latch with a wide operating voltage range from 1.76V to 5.5V. It offers excellent performance with a low noise margin and a large input common-mode range. The device is highly immune to noise and can be used in noisy environments.The SN74LVTH573GQNR device consists of eight latches with 3-state outputs, each controlled by a common ENABLE input. A single latch consists of a pair of cross-coupled NAND gates. When the ENABLE input is at a high logic level, the output of the NAND gates are typically high.When the ENABLE input is low, the Q and Q’ outputs from the NAND gates are held to a low logic level. Because the ENABLE input controls all eight latches simultaneously, all the outputs of the SN74LVTH573GQNR are either in High or Low logic level or in the High Impedance state. The 3-state outputs of the latch make it useful in bus oriented systems. When the ENABLE input is at a high level all the outputs are in a high-impedance, or tri-state, mode. The bus-oriented system can then be driven by other system components.Another useful feature of the SN74LVTH573GQNR is its push-pull outputs that helps it drive capacitive or resistive loads directly. This feature helps reduce the external circuit on a board. The push-pull outputs drive a low impedance load such as a capacitive or a resistive one, and when the output is in the three-state, the internal strength of the output is disabled.The SN74LVTH573GQNR also provides a very low power dissipation, enabling it to be used in mobile and battery-powered equipments. Additionally, the device is designed with an adjustable power saving mode that automatically disables the output of unused latches, reducing the overall power consumption.In addition, the SN74LVTH573GQNR has a built-in clock feature which enables the latch to sense and capture input data while the enable signal is low. The clock signal can also be used to control the enable signal, allowing the device to operate without the enable signal. In summary, the SN74LVTH573GQNR is a versatile 3-state octal latch IC with 3-state outputs and adjustable power saving mode. It is suitable for use in portable, automotive, and industrial applications and is designed to operate with a low-noise margin and a wide input common-mode range. Moreover, the device provides a very low power dissipation and has built-in clocks which enable it to sense and capture input data.
