Product Overview: Texas Instruments 74LVC573APWR

The Texas Instruments 74LVC573APWR is a high-performance, octal transparent D-type latch that is part of the 74LVC family. This integrated circuit is designed for 2.7 V to 3.6 V VCC operation, making it suitable for low-voltage applications that require a balance between power consumption and speed. It is particularly useful in the interfacing of 3.3V systems to 5V systems, offering a convenient level-shifting solution.

With its wide operating voltage range and the ability to tolerate 5V inputs when powered down, the 74LVC573APWR is versatile and highly adaptable to different system requirements. The device features eight latches with 3-state outputs for bus-oriented applications. The 3-state outputs ensure that the latches can either hold data input when the latch-enable (LE) input is high, output data when the output-enable (OE) input is low, or be in a high-impedance state when OE is high, preventing bus conflict.

The 74LVC573APWR operates at a high speed with a typical propagation delay time of only 3.7 ns when powered by a 3.3V supply, and it can drive up to 24 mA of output sink current. This makes it suitable for high-speed data storage and transfer operations in computing and digital systems.

The device is offered in a TSSOP (Thin Shrink Small Outline Package) with 20 pins, identified by the PWR suffix in its part number. This compact package makes it ideal for space-constrained applications. The 74LVC573APWR also features a wide temperature range, functioning optimally between -40°C and 85°C, which allows for reliable performance in various environmental conditions.

Key features of the Texas Instruments 74LVC573APWR include:

• 8-bit transparent D-type latch with 3-state outputs
• Operating Voltage Range: 2.7 V to 3.6 V
