Overview
The 74LVC573APW-Q100J, produced by Nexperia USA Inc., is an 8-bit D-type transparent latch with 3-state outputs. This device is designed to operate in a wide range of supply voltages from 1.2 to 3.6 V, making it versatile for various applications. It features latch enable (LE) and output enable (OE) inputs, allowing for precise control over data storage and output states. The device is particularly useful in mixed 3.3 V and 5 V environments due to its 5 V tolerant inputs and outputs.

Key Features
- Octal D-type transparent latch: Allows data to pass through when the latch enable (LE) is HIGH, and stores data when LE is LOW.
- 3-state outputs: Outputs can be set to a high-impedance OFF-state using the output enable (OE) input.
- 5 V tolerant inputs/outputs: Compatible with both 3.3 V and 5 V devices, making it suitable for mixed voltage environments.
- Schmitt-trigger action: Tolerant of slower input rise and fall times.
- Low power consumption: CMOS technology ensures low power usage.
- IOFF circuitry: Enables partial power-down mode operation and prevents backflow current when the device is powered down.
- High-impedance when VCC = 0 V: Ensures safe operation during power-down states.
- Flow-through pinout architecture: Simplifies PCB layout.
- ESD protection: Compliant with ANSI/ESDA/JEDEC standards, exceeding 2000 V for HBM and 1000 V for CDM.
Applications
- Mixed voltage systems: Ideal for environments where both 3.3 V and 5 V devices are used.
- Automotive and industrial systems: AEC-Q100 qualified, making it suitable for automotive and industrial applications.
- Data storage and transmission: Useful in applications requiring temporary data storage and transmission.
- Low power designs: Suitable for battery-powered devices and other low power consumption applications.
