SN74LVTH573GQNR Octal Transparent D-Type Latches with 3-State Outputs

The SN74LVTH573GQNR from Texas Instruments is a high-performance, octal transparent D-type latch that is designed to provide storage and isolation for eight data input lines. This component is part of the LVTH family, which stands for Low-Voltage BiCMOS Technology with TTL-compatible inputs. It allows for a 3.3V operation while maintaining 5V tolerant inputs, making it suitable for mixed-voltage applications.

Key Features:

• Device Type: Octal transparent D-type latch
• Output Type: 3-State, allowing for bus-oriented applications
• Logic Family: LVTH - Low-Voltage BiCMOS Technology
• Operating Voltage: 2.7V to 3.6V, with 5V tolerant inputs
• Package: Supplied in a Thin Shrink Small-Outline Package (TSSOP)
• Pin Count: 20
• Propagation Delay Time: Fast propagation delay times, enhancing system speed
• Operating Temperature Range: -40°C to +85°C
• RoHS: Compliant with RoHS directive

Applications:

The SN74LVTH573GQNR is ideal for a wide range of applications, particularly where high-speed, low-power latch functions are required. Some common applications include:

• Data storage and retrieval systems
• Communication systems
• Servers and networking equipment
• Industrial control systems
• Portable electronics

Product Description:

The SN74LVTH573GQNR features a transparent latch operation, which means that while 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. An additional feature of this device is the 3-state outputs, which do not load the bus when the latch-enable (LE) and output-enable (OE) inputs are held at a high logic level. This makes it easy to set up bus lines in a system. Texas Instruments assures high-quality performance with this device, which is tested for specified parameters over the -40°C to +85°C temperature range.
