74ACT573MTCX

Latches Overview

The onsemi 74ACT573MTCX is an octal D-type transparent latch featuring buffered common Latch Enable (LE) and Output Enable (OE) inputs. It provides eight 3-STATE outputs capable of sourcing or sinking 24mA, with TTL-compatible inputs for the ACT series. The device operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 20-Lead Thin Shrink Small Outline Package (TSSOP).

Latches Feature Summary

• Features 3-STATE outputs suitable for bus interfacing applications.
• Inputs and outputs are positioned on opposite sides of the package to facilitate microprocessor interface design.
• Includes buffered common Latch Enable and Output Enable control signals.

Latches Applications

• Microprocessor input/output port expansion.
• Bus interfacing systems requiring high-impedance states.
• Octal data latching circuits.

Latches Procurement Notes

Verify that the specific ordering suffix 'X' corresponds to tape and reel packaging as defined in the manufacturer's documentation. Confirm RoHS compliance status and ensure the component meets JEDEC moisture sensitivity level requirements for your assembly process before procurement.

Latches Selection Notes

Select this component when an octal latch with 3-STATE outputs and TTL-compatible inputs is required. Ensure the operating environment stays within the -40°C to +85°C temperature range and the supply voltage remains between 4.5V and 5.5V. Verify package compatibility with the 20-Lead TSSOP footprint.

Latches Part Context

This part belongs to the 74ACT logic family, characterized by high-speed operation and CMOS technology with TTL-compatible inputs. It is functionally identical to the 74AC573 but optimized for 5V operation. The device serves as a standard solution for parallel data storage in digital logic systems.

Latches Replacement Considerations

The datasheet notes functional identity with the 74ACT373, though pinout orientation differs. Direct substitutes may include other 74ACT573 variants from different manufacturers, provided they match the 20-TSSOP package and electrical specifications.
