74ACT158SCX

Signal Switches, Multiplexers, Decoders Overview

The Fairchild Semiconductor 74ACT158SCX is a high-speed, low-power octal D-type flip-flop featuring separate D-type inputs for each flip-flop and 3-STATE outputs for bus-oriented applications. A buffered Clock (CP) and Output Enable (OE) are common to all flip-flops. The device has TTL-compatible inputs.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the manufacturer part number against official Fairchild or onsemi documentation to ensure authenticity. Confirm that the package type matches the required SOIC-20 form factor. Check RoHS compliance status if environmental regulations apply to your specific deployment. Ensure input voltage levels align with the specified TTL-compatible requirements for proper logic interface operation.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when an octal D-type flip-flop with tri-state outputs is required for bus systems. It offers buffered clocking and TTL-compatible inputs. Consider the 74AC374 variant if a reset version is needed, or the 74ACT377 if clock enable functionality is preferred over simple tri-state control for the application design.

Signal Switches, Multiplexers, Decoders Part Context

This component belongs to the 74ACT series of logic integrated circuits. It is functionally related to other octal devices in the family, such as the 74AC374 and 74ACT374, which share similar output drive capabilities and pinout configurations but may differ in control features like resets or clock enables.
