Product Overview: SN74LVTH573DBR
The SN74LVTH573DBR is a high-performance, octal transparent D-type latch designed and manufactured by Texas Instruments. This product is part of TI's LVTH family, which stands for Low-Voltage, Tolerant High-speed. The device is optimized for operation at 3.3V, but it can also tolerate 5V signals, making it suitable for mixed-voltage applications. It is designed to provide a seamless interface between 3.3V and 5V systems in a wide array of digital circuits.
The SN74LVTH573DBR offers 8 D-type latches with 3-state outputs. When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs. A separate output-enable (OE) input controls the 3-state outputs. When OE is low, the outputs are active and reflect the data that has been latched. When OE is high, the outputs are in a high-impedance state, which is particularly useful for sharing bus lines and connecting multiple devices without risking bus contention.
The device is housed in a DBR package, which is a 20-pin SSOP (Shrink Small Outline Package) that offers a compact footprint while ensuring good thermal performance and easy integration into surface-mounted technology (SMT) processes. The SN74LVTH573DBR is characterized for operation from -40°C to 85°C, making it reliable for use in industrial applications with challenging temperature environments.
Key features of the SN74LVTH573DBR include the ability to drive up to 15 LSTTL loads, ±24-mA output drive at 3.3 V, and bus hold on data inputs to eliminate the need for external pull-up/pull-down resistors. This makes it a great choice for designers looking for a robust latch that can maintain signal integrity in a noisy environment.
Overall, the SN74LVTH573DBR is a versatile, high-quality component that upholds the Texas Instruments reputation for creating reliable, industry-leading semiconductor products. Whether it's being used in computing, telecommunication, or consumer electronics, this transparent latch is engineered to meet the demands of complex digital systems.
