74ACT841SC

Latches Overview

The Fairchild Semiconductor 74ACT841SC is a 10-bit transparent latch featuring 3-STATE outputs, designed for bus interface applications. It operates within a supply voltage range of 4.5V to 5.5V and supports through-hole mounting in a 24-SOP package. The device provides ten D-type latches with separate data inputs and common latch enable controls. It is RoHS compliant and suitable for industrial temperature ranges.

Latches Feature Summary

• Provides ten D-type latches with 3-STATE outputs for bus-oriented applications
• Transparent operation allows data to pass directly when Latch Enable is HIGH
• TTL-compatible inputs ensure compatibility with standard logic families
• Designed to eliminate extra buffering packages for wider data widths

Latches Applications

• Bus interface latch circuits
• Data storage in microprocessor systems
• Wide data width buffering applications

Latches Procurement Notes

Verify the specific suffix SC indicates the SOP-24 package configuration. Confirm RoHS compliance status matches current regulatory requirements. Check manufacturer discontinuation notices as legacy ACT series parts may have limited availability or end-of-life status. Ensure pinout compatibility with existing PCB layouts before procurement.

Latches Selection Notes

Select this component when a 10-bit transparent latch with tri-state capability is required. It serves as a direct replacement for buffered latch designs that previously required multiple discrete components. Consider the 24-SOP package constraints for board space. Verify input voltage levels match the system's logic family standards.

Latches Part Context

This part belongs to the 74ACT series of high-speed CMOS logic devices. It is functionally related to other octal and decalatch variants like the 74ACT842. The device replaces older bipolar TTL equivalents with lower power consumption while maintaining similar speed characteristics. It is manufactured by Fairchild Semiconductor.

Latches Replacement Considerations

Direct substitutes include the 74ACT841SJ (SOIC-24) and 74ACT841MSA (SSOP-24). Verify package dimensions and pin spacing compatibility. Ensure functional equivalence regarding propagation delay and output drive strength.
