SN74LV573ATDBR Octal Transparent D-Type Latches with 3-State Outputs

The SN74LV573ATDBR is a high-performance, octal transparent D-type latch designed by Texas Instruments, which is renowned for its reliability and innovation in the semiconductor industry. This integrated circuit is part of the 74LV family, which is characterized by low-voltage operation and is optimized for use in 3.3V systems. With its transparent latches, the device allows data to flow directly from the input to the output when the latch-enable (LE) input is high, and it latches data when LE is low.

Constructed using an advanced BiCMOS technology, the SN74LV573ATDBR offers superior performance with a typical propagation delay of only 4.5 ns and a maximum of 8.8 ns, ensuring fast and efficient data handling in critical applications. This device is particularly suitable for temporary storage of data, buffering, and data transmission for systems that require high-speed and low-power operation.

The SN74LV573ATDBR features 3-state outputs, which means that besides the usual high and low logic levels, the outputs can also be placed in a high-impedance state. This high-impedance state is crucial for bus-oriented applications, as it allows multiple devices to share the same data lines without interference.

Key specifications of the SN74LV573ATDBR include:

• 8-bit wide transparent D-type latches.
• 3.3V operation with 5V tolerant inputs.
• Output capability: bus driver.
• Edge-triggered latching on the low-to-high transition of the LE signal.
• OE (Output Enable) bar input for easy cascading and output control.
• Maximum operating frequency: 110 MHz.
• Low power consumption with ICC of only 80 µA maximum.

The device comes in a TSSOP (Thin Shrink Small Outline Package) form factor with the DBR suffix indicating the reel packaging for the product, which is ideal for automated assembly processes. The SN74LV573ATDBR is suitable for a wide range of applications, including personal computers, servers, networking equipment, and industrial control systems, where high-speed, low-power operation is a necessity.

Overall, the SN74LV573ATDBR from Texas Instruments is a reliable and efficient solution for designers looking to implement transparent latches with 3-state outputs in their digital systems.
