74ACT573SJX

Latches Overview

The onsemi 74ACT573SJX is an octal D-type latch with 3-STATE outputs, part of the 74ACT logic series. It features a 20-Lead Small Outline Package (SOP) compliant with EIAJ TYPE II standards. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to +85°C. Key electrical parameters include a propagation delay of 10.5 ns at 5V, a maximum quiescent supply current of 4 µA, and output drive capabilities sourcing or sinking 24 mA. Inputs are TTL-compatible.

Latches Feature Summary

• Features inputs and outputs positioned on opposite sides of the package to facilitate easy interface with microprocessors.
• Provides 3-STATE outputs suitable for bus interfacing applications.
• Includes buffered common Latch Enable (LE) and Output Enable (OE) inputs.

Latches Applications

• Input or output port for microprocessors
• Bus interfacing

Latches Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the SOP-20 package matches the EIAJ TYPE II specification. Ensure the ordering suffix 'X' corresponds to the required tape and reel packaging format. Check RoHS compliance status against current JEDEC J-STD-020B standards before finalizing procurement.

Latches Selection Notes

Select this component when designing systems requiring octal latching with high-speed performance and bus isolation. The 74ACT series offers TTL-compatible inputs while maintaining AC-level speed characteristics. Consider the specific SOP-20 footprint requirements and verify that the 4.5V to 5.5V supply voltage aligns with the system power architecture.

Latches Part Context

This device belongs to the 74ACT family of high-speed CMOS logic devices manufactured by onsemi. It is functionally identical to the 74AC373 and 74ACT373 but distinguishes itself through the physical arrangement of pins, placing inputs and outputs on opposite sides of the package. This layout simplifies PCB routing for microprocessor interfaces.

Latches Replacement Considerations

Functionally equivalent parts include the 74AC373 and 74ACT373. Verify pinout compatibility regarding the opposite-side input/output configuration before substitution.
