74ACT533MTCX

Latches Overview

The onsemi 74ACT533MTCX is an octal transparent latch with 3-STATE outputs, housed in a 20-lead Thin Shrink Small Outline Package (TSSOP). 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 eight D-type latches controlled by Latch Enable (LE) and Output Enable (OE) inputs. Propagation delay from data input to output ranges from 2.0ns to 8.5ns at 5.0V. The outputs can source or sink up to 24mA, ensuring compatibility with bus-oriented system applications.

Latches Feature Summary

• Contains eight transparent latches with 3-STATE outputs for bus organization
• Outputs capable of sourcing and sinking 24mA current
• Inputs are TTL-compatible for direct interface with standard logic
• Reduced ICC and IOZ characteristics compared to previous generations

Latches Applications

• Bus organized system applications
• Buffering memory address registers
• Driving bus lines in digital circuits

Latches Procurement Notes

Verify the specific package variant, as the base part number covers multiple packages including TSSOP, SOIC, and PDIP. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design margins account for the specified absolute maximum ratings to prevent device damage during operation.

Latches Selection Notes

Select this component when an octal latch with high-drive 3-STATE outputs is required for bus systems. The ACT series offers faster switching speeds than HC variants while maintaining TTL-compatible input thresholds. Verify that the 20-lead TSSOP footprint fits the target PCB layout constraints before finalizing the design.

Latches Part Context

This device belongs to the 74ACT logic family, characterized by CMOS technology with TTL-compatible inputs. It serves as the non-inverted counterpart to the 74ACT537 and is functionally related to the 74ACT373, though it lacks inverted outputs. The MTCX suffix specifically denotes the Tape and Reel packaging format within the 20-lead TSSOP option.

Latches Replacement Considerations

Direct substitutes include the 74ACT533SCX (SOIC-14/20 variant) and 74ACT533PCX (PDIP variant) from the same manufacturer. Cross-brand equivalents such as the SN74ACT533 from Texas Instruments may be considered if pinout and electrical specifications match exactly.
