Description
Key features include:
- Eight latches in a single package
- 3-state outputs for bus-oriented applications
- Direct interface to TTL devices
- High noise immunity
- Low power consumption
The SN74HC573ADWR is often used in applications requiring temporary data storage, data buffering, and bus interfacing. Its transparent latch operation ensures that data at the input is transferred to the output when the latch-enable (LE) input is high. When LE is low, the output remains unchanged regardless of input changes.
Packaged in a SOIC-20 (DW) form, it is suitable for surface-mount assembly, meeting industry-standard dimensions. Its wide operational temperature range makes it reliable for use in various environmental conditions.

Features
1. High-Speed Performance: It provides fast logic processing, suitable for various digital applications.
2. Octal Configuration: Consists of eight latches for handling multiple data lines simultaneously.
3. 3-State Outputs: Allows the outputs to be set to a high-impedance state, enabling multiple outputs to connect to a common bus without interference.
4. Wide Supply Voltage Range: Operates across a range of 2V to 6V, offering flexibility in different systems.
5. Low Power Consumption: Its CMOS technology ensures efficient power usage.
6. Latch Enable (LE) Input: The device latches the input data when the LE is high.
7. Output Enable (OE) Control: When OE is low, the outputs are enabled; when high, outputs are in high-impedance state.
8. Compatibility: Compatible with TTL logic levels, making it versatile for integration.
9. Temperature Range: Operates reliably over a wide temperature range, typical for industrial applications.
These features make it suitable for use in buffer, storage register, and bus interface applications.
Pinout
Pin Count:
- Total pins: 20
Key Functions:
- Inputs:
- Eight data inputs (D0 to D7)
- Latch enable input (LE)
- Output enable input (OE)
- Outputs:
- Eight 3-state outputs (Q0 to Q7)
Function:
- The device is used to latch the data present at the input pins when the latch enable (LE) input is high. When LE is low, the data inputs can change without affecting the latch outputs.
- The output enable (OE) input controls the state of the outputs. When OE is low, the outputs reflect the latches' data. When OE is high, the outputs are in a high-impedance state, effectively disconnecting them from the circuit.
The SN74HC573ADWR is commonly used in applications requiring temporary data storage and bus interfacing.
