Description
The SN74HCT573PWR features a transparent latch, meaning data at the input is directly passed to the output when the latch enable (LE) is high. When LE is low, the data is latched and maintained at the output until it is updated again. The outputs can be placed in a high-impedance state via the output enable (OE) pin, allowing for easy integration into systems with shared buses.
Packaged typically in a TSSOP-20, the SN74HCT573PWR is suitable for compact designs. Its high-speed operation and low power consumption make it ideal for use in various digital applications requiring fast and reliable data latching.

These alternatives are similar in functionality, offering D-type latching with 3-state outputs, but check datasheets for specific electrical and performance characteristics to ensure compatibility with your application.
Features
1. Logic Family: High-speed CMOS (HCT), ensuring compatibility with TTL logic levels.
2. Voltage Range: Operates at a supply voltage range of 4.5V to 5.5V.
3. Output Type: 3-state, allowing the outputs to be in a high-impedance state, useful for bus-oriented applications.
4. Latch Enable (LE) and Output Enable (OE): Offers control over latching and output states, enhancing flexibility.
5. Propagation Delay: Typically offers fast switching with low propagation delay.
6. Inputs: Features eight transparent latches, which capture data when the latch enable is high.
7. Package Type: Available in a TSSOP (Thin Shrink Small Outline Package) for compact designs.
8. Temperature Range: Supports an operating temperature range suitable for commercial applications.
9. Power Consumption: Low power consumption due to CMOS technology.
The SN74HCT573PWR is ideal for applications requiring data latching and bus interfacing in a compact and efficient manner.
Pinout
Regarding its pin configuration:
- It comes in a 20-pin package.
- The primary functions of the pins are as follows:
- Eight D input pins for data inputs.
- Eight Q output pins for data outputs.
- A LE (Latch Enable) pin to control the latch operation; when high, the latch is transparent.
- An OE (Output Enable) pin for controlling the output state; when low, the outputs follow the latch state, and when high, outputs are in high-impedance state.
- VCC and GND pins for power supply and ground.
The SN74HCT573PWR is commonly used in digital systems for temporarily storing and moving data.
