N74F573DB,118

Latches Overview

The N74F573DB,118 is an octal transparent latch with 3-State outputs manufactured by NXP USA Inc. It operates within a supply voltage range of 4.5V to 5.5V and supports a commercial temperature range of 0°C to +70°C. The device features a typical propagation delay of 5.0ns from data inputs to outputs and a total typical supply current of 35mA. It utilizes a 20-pin Plastic SSOP package (SOT339-1) designed for surface mount applications.

Latches Feature Summary

• Broadside pinout configuration facilitates printed circuit board layout and microprocessor interfacing
• Independent Enable and Output Enable control gates manage latch transparency and bus isolation
• Glitch-free 3-State outputs during power-up and power-down sequences

Latches Applications

• Microprocessor input or output port expansion
• Bus interfacing for heavily loaded 3-State buses
• Driving MOS memories or MOS microprocessors

Latches Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and environmental ratings. Confirm component status as obsolete or discontinued before finalizing procurement plans. Ensure compatibility with existing design constraints regarding the 20-pin SSOP footprint and recommended operating conditions.

Latches Selection Notes

Select this component when a broadside pinout is required for improved PCB routing compared to standard parallel layouts. Consider the 3-State buffer capability for bus sharing applications. Verify that the 0°C to +70°C commercial temperature range meets system requirements. Check for functional equivalents if the specific part number is no longer in production.

Latches Part Context

This component belongs to the 74F logic family, characterized by high-speed operation. It serves as the broadside pinout version of the 74F373. The device integrates eight D-type latches coupled to three-state output buffers, allowing independent control of data storage and output drive states via separate enable signals.
