74HCT573D,652

Latches Overview

The Nexperia 74HCT573D,652 is an octal D-type transparent latch featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device utilizes TTL input levels and provides common output enable functionality for bus-oriented applications. It is housed in a 20-lead plastic small outline package (SO20) with a body width of 7.5 mm.

Latches Feature Summary

• Features eight D-type transparent latches with independent data inputs and corresponding outputs.
• Includes a common three-state output enable input for managing bus-oriented applications.
• Inputs are equipped with clamp diodes to facilitate interfacing with voltages exceeding the supply voltage.

Latches Applications

• Used as an input or output port for microprocessors and microcomputers.
• Implemented in bus-oriented systems requiring controlled data storage and transmission.
• Utilized in digital logic circuits necessitating parallel data latching with tri-state control.

Latches Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package type and temperature range. Ensure compatibility with system voltage requirements and interface standards before integration. Confirm current product status and availability through authorized distribution channels.

Latches Selection Notes

Select this component when designing systems requiring octal data storage with high-impedance output control. Verify that the TTL input voltage thresholds align with the driving logic family. Consider the thermal performance and power dissipation characteristics relative to the operating environment and package constraints.

Latches Part Context

This part belongs to the 74HCT series of CMOS logic devices, designed for compatibility with TTL logic levels while maintaining CMOS low power consumption. The 74HCT573 variant specifically provides octal latching capabilities, distinguishing it from other logic families by its combination of speed, noise immunity, and bus drive capability.

Latches Replacement Considerations

Cross-reference with other manufacturers' 74HCT573 equivalents to ensure pinout and electrical parameter compatibility. Verify package dimensions and lead spacing match existing board layouts. Confirm functional equivalence regarding propagation delays and output drive strengths.
