N74F573N,602

Latches Overview

The N74F573N,602 is an octal transparent latch with 3-State outputs manufactured by NXP USA Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a commercial temperature range of 0°C to +70°C. The device features a typical propagation delay of 5.0 ns from data inputs to outputs and a total typical supply current of 35 mA. It utilizes a 20-pin Plastic DIP package (SOT146-1) and provides high-level output currents of -3 mA and low-level output currents of 24 mA.

Latches Feature Summary

• Broadside pinout configuration facilitates PC board layout and microprocessor interfacing
• Independent Enable and Output Enable control gates for flexible bus management
• Glitch-free 3-State outputs during power-up and power-down sequences

Latches Applications

• Microprocessor input or output port implementation
• Bus interfacing applications requiring 3-State isolation
• High-speed replacement for legacy N8TS805 and N8TS806 components

Latches Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and environmental ratings. Confirm component availability status as manufacturing lifecycles may change. Ensure compatibility with existing system voltage levels and logic families before integration.

Latches Selection Notes

Select this component when a broadside pinout is required for improved PCB routing compared to standard pinouts. Consider the 3-State buffer capability for shared bus architectures. Evaluate the 74F series speed characteristics against system timing requirements and power consumption limits.

Latches Part Context

This part belongs to the 74F logic family, characterized by high-speed bipolar technology. It serves as a functional equivalent to the 74F373 but distinguishes itself through its specific pin arrangement designed to simplify connections to microprocessors and memory systems.

Latches Replacement Considerations

The datasheet identifies the 74F373 as the functional equivalent with a different pinout. Legacy replacements include the N8TS805 and N8TS806.
