Key Specifications
| Type Number | VCC (V) | Logic Switching Levels | Output Drive Capability (mA) | tpd (ns) | fmax (MHz) | Power Dissipation Considerations | Tamb (°C) | Package Name |
|---|---|---|---|---|---|---|---|---|
| 74HC573PW-Q100 | 2.0 - 6.0 | CMOS | ± 7.8 | 14 | 8 | Low | -40 ~ 125 | TSSOP20 |
Key Features
- Latch Enable and Output Enable Inputs: The device features latch enable (LE) and output enable (OE) inputs. When LE is HIGH, data at the inputs enter the latches, and when LE is LOW, the latches store the information. A HIGH on OE causes the outputs to assume a high-impedance OFF-state.
- 3-State Non-Inverting Outputs: Suitable for bus-oriented applications with 3-state non-inverting outputs.
- High-Speed CMOS: High-speed Si-gate CMOS device with low power dissipation.
- Automotive Qualified: Qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and operates from -40 °C to +125 °C.
- ESD Protection: Complies with JEDEC standards for ESD protection, exceeding 2000 V for HBM and 1000 V for CDM.
- Multiple Package Options: Available in various packages including TSSOP20, DHVQFN20, and SO20.
- Input Protection: Inputs include clamp diodes, enabling the use of current limiting resistors to interface inputs to voltages in excess of VCC.
Applications
- Automotive Systems: Suitable for use in automotive applications due to its AEC-Q100 qualification.
- Microprocessor and Microcomputer Interfaces: Useful as input or output ports for microprocessors and microcomputers.
- Bus-Oriented Applications: Ideal for bus-oriented applications with its 3-state non-inverting outputs.
- General Logic Circuits: Can be used in various general logic circuits requiring high-speed and low power consumption.
