74ACT841SCX

Latches Overview

The Fairchild Semiconductor 74ACT841SCX is a 10-bit transparent latch with 3-STATE outputs, belonging to the ACT series. It utilizes CMOS technology and is housed in a 24-SOIC surface-mount package (0.295 inch width). The device features TTL-compatible inputs and provides separate D-type inputs for each latch. It includes a buffered Clock (CP) and Output Enable (OE) common to all latches. The component operates within a voltage range of 4.5V to 5.5V and supports an operating temperature range of -40°C to 85°C.

Latches Feature Summary

• Provides 10-bit data storage capability via transparent latch architecture
• Features 3-STATE outputs suitable for bus-oriented applications
• Incorporates TTL-compatible input levels for system integration
• Utilizes buffered clock and output enable signals for synchronized control

Latches Applications

• Bus interface latch designs requiring extended data width
• Buffering existing latch circuits in digital systems
• Data storage modules in microprocessor-based systems
• High-speed low-power logic applications

Latches Procurement Notes

Verify the specific suffix SCX confirms the SOIC-24 surface mount package and lead-free status. Confirm RoHS compliance documentation matches current regulatory requirements. Ensure the supplier source is authorized to guarantee original Fairchild or Microchip manufacturing quality. Check for any obsolescence notices as this component may be discontinued or superseded by newer equivalents.

Latches Selection Notes

Select this component when a 10-bit wide latch with tri-state outputs is required for bus applications. The ACT series offers high speed and low power consumption compared to standard TTL. The SOIC package is appropriate for automated surface-mount assembly processes. Verify that the 4.5V to 5.5V supply voltage aligns with the target system design constraints.

Latches Part Context

The 74ACT841 is part of the Fairchild ACT series of advanced CMOS logic devices. This series is designed to provide high-speed performance with low power dissipation. The 74ACT841 specifically addresses the need for wider data buses without requiring multiple parallel packages. It serves as a direct replacement for older bipolar technologies in modern digital designs.

Latches Replacement Considerations

The 74F841PC is a PDIP24 through-hole equivalent from the F/FAST series. The 74AC841 is the non-TTL input variant. Verify pin compatibility and electrical characteristics before substitution.
