74F573SJX

Latches Overview

The onsemi 74F573SJX is an octal D-type latch with 3-state outputs, manufactured using high-speed ECL-compatible technology. It features buffered common Latch Enable (LE) and Output Enable (OE) inputs. The device operates within a supply voltage range of +4.5V to +5.5V. Propagation delays from Dn to On are typically 3.7ns at VCC=5.0V, while LE to On delays are typically 5.2ns. The SOP-20 package allows for inputs and outputs on opposite sides of the package.

Latches Feature Summary

• High-speed operation suitable for microprocessor interface applications
• Inputs and outputs located on opposite sides of the package for easy routing
• Functionally identical to the 74F373 but with a different pinout configuration
• Provides 3-state outputs specifically designed for bus interfacing

Latches Applications

• Microprocessor input or output port implementation
• Bus interfacing systems requiring tri-state control
• Digital logic circuits utilizing octal latching functionality

Latches Procurement Notes

Verify component authenticity through authorized distributors as this part originates from Fairchild Semiconductor history. Confirm RoHS compliance status and specific ordering suffixes against current manufacturer documentation. Ensure the SOP-20 package variant matches design requirements before procurement.

Latches Selection Notes

Select this component when ECL-compatible speed is required alongside standard TTL logic levels. The 74F573SJX differs from the 74F373 in pin arrangement; verify schematic compatibility. Consider the 3-state buffer capability for bidirectional bus architectures where high impedance states are necessary.

Latches Part Context

This component belongs to the 74F series of high-speed logic devices. It serves as an alternative to the 74F373, offering identical logical operations but distinct physical pin assignments. The 'SJX' designation indicates the Small Outline Package (SOP) form factor with tape and reel packaging.

Latches Replacement Considerations

The 74F373 is functionally equivalent but utilizes a different pinout. Verify pin compatibility before substitution. Other 74F series latches may offer similar speeds but require checking specific electrical characteristics and package dimensions.
