Description
The SN74LV573APWR features eight latches that are transparent when the latch-enable (LE) input is high. When LE is low, the data present at the D inputs are stored, and the outputs remain unchanged. The device includes 3-state outputs, controlled by the output-enable (OE) input, allowing for easy interfacing with a bus-oriented system.
Housed in a TSSOP package, the SN74LV573APWR is designed for surface-mount applications, saving space on printed circuit boards. Its low power consumption and high noise immunity make it ideal for various applications, including memory interfacing, data buffering, and peripheral control in embedded systems.
Equivalent
1. 74HC573 from NXP
2. CD74HCT573 from Texas Instruments
3. MC74HC573 from ON Semiconductor
4. TC74HC573 from Toshiba
5. HEF473 from Nexperia
These alternatives offer similar functionality as octal D-type transparent latches with 3-state outputs, but it's crucial to check datasheets for pin compatibility and electrical characteristics before substituting.
Features
1. Supply Voltage: Operates with a supply voltage range of 2 V to 5.5 V, making it compatible with a wide range of systems.
2. Low Power Consumption: Designed for low power applications, it features reduced power dissipation.
3. Latch Enable and Output Control: Features an active-high latch enable input and an active-low output enable input, allowing for flexible data handling and output control.
4. 3-State Outputs: Provides 3-state outputs, allowing for direct bus interfacing and minimizing bus loading.
5. High-Speed Operation: Capable of high-speed operation with a maximum frequency of 100 MHz, suitable for fast data processing.
6. Wide Operating Temperature Range: Operates effectively within a temperature range of -40°C to 85°C.
7. CMOS Technology: Utilizes CMOS technology for improved noise immunity and minimal static power consumption.
8. Package Type: Available in TSSOP-20 package, facilitating compact PCB design.
These features make it suitable for a variety of digital applications requiring efficient latch operations and bus interfacing.
Pinout
Key functions and features include:
1. Latch Inputs (D0-D7): These are the data inputs for the eight latches.
2. Outputs (Q0-Q7): These are the 3-state outputs corresponding to each latch.
3. Output Enable (OE\): This active-low input controls the state of the outputs. When OE\ is low, the outputs reflect the state of the latches. When OE\ is high, the outputs are in a high-impedance state.
4. Latch Enable (LE): This input controls when data is latched. When LE is high, data on the inputs is transferred to the outputs. When LE is low, the last data present is retained.
The SN74LV573APWR operates on a supply voltage range of 2.0 V to 5.5 V and is commonly used in tasks requiring temporary data storage or buffering.
