74ACT533SC

Latches Overview

The onsemi 74ACT533SC is an octal transparent latch with 3-STATE outputs, manufactured by Fairchild Semiconductor. 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 latches in a single package with inverted data inputs. Propagation delays from Dn to On range from 2.0ns to 8.5ns depending on conditions. Output drive capability reaches 24mA, while quiescent supply current is limited to 40µA maximum.

Latches Feature Summary

• Contains eight transparent latches with 3-STATE outputs for bus organized system applications
• Outputs source and sink 24 mA to drive bus lines or buffer memory address registers
• Features TTL-compatible inputs and reduced ICC and IOZ power consumption
• Functions as the inverted version of the ACT373 latch

Latches Applications

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

Latches Procurement Notes

Verify the manufacturer origin, as this component was originally produced by Fairchild Semiconductor before acquisition by onsemi. Confirm the specific package type (SOIC-20) matches the design requirements. Ensure compatibility with existing logic families and check for any lifecycle status changes regarding availability or obsolescence.

Latches Selection Notes

Select this component when an octal latch with high-drive 3-STATE outputs is required for bus systems. It is suitable for designs needing TTL-compatible inputs and low quiescent current. Consider the inverted nature of the inputs compared to standard non-inverting latches like the ACT373 during schematic design.

Latches Part Context

This part belongs to the 74ACT family of advanced CMOS logic devices. It provides high-speed performance with standard CMOS compatibility. The SOIC-20 package allows for surface-mount assembly, fitting into compact electronic designs requiring multiple latching functions within a single integrated circuit footprint.

Latches Replacement Considerations

The datasheet identifies the 74ACT373 as the non-inverted counterpart. Verify pinout compatibility if substituting with other octal latches. Check equivalent parts from other manufacturers that match the 74ACT logic family specifications and SOIC-20 package dimensions.
