74ACT573PC

Latches Overview

The onsemi 74ACT573PC is an octal latch with 3-STATE outputs housed in a 20-Lead Plastic Dual-In-Line (PDIP) package. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature from -40°C to +85°C. The device features buffered common Latch Enable (LE) and Output Enable (OE) inputs, providing TTL-compatible inputs for the ACT series. Outputs can source or sink 24mA, with propagation delays typically ranging from 6.0ns to 10.5ns at 5.0V.

Latches Feature Summary

• Inputs and outputs are positioned on opposite sides of the package to facilitate easy interface with microprocessors.
• Functionally identical to the 74AC373 and 74ACT373 devices but distinguished by the specific pinout arrangement.
• Features 3-STATE outputs suitable for bus interfacing applications.

Latches Applications

• Input or output port for microprocessors
• Bus interfacing

Latches Procurement Notes

Verify that the ordering suffix 'PC' corresponds specifically to the 20-Lead PDIP package as defined in the datasheet. Confirm the logic family is ACT for TTL compatibility. Ensure the component meets the required JEDEC MS-001 standard dimensions for this package type before finalizing procurement specifications.

Latches Selection Notes

Select the 74ACT573PC when a PDIP form factor is required for through-hole mounting. This variant provides the same logical functionality as surface-mount versions but utilizes a dual-in-line configuration. Ensure the design environment accommodates the larger footprint compared to SOIC or SOP alternatives while maintaining the specified electrical characteristics.

Latches Part Context

This component belongs to the 74ACT573 series of octal latches manufactured by Fairchild Semiconductor, now part of onsemi. The series includes variants in SOIC, SOP, TSSOP, and PDIP packages. The 74ACT573PC specifically denotes the plastic dual-in-line version, offering a robust mechanical solution for legacy or high-reliability through-hole designs requiring octal data storage capabilities.

Latches Replacement Considerations

The 74ACT573SC serves as a functional substitute in a 20-Lead SOIC package. The 74ACT573SJ is available in a 20-Lead SOP package. The 74ACT573MTC offers a 20-Lead TSSOP option. All variants share identical logical operations and electrical specifications.
