Overview
The 74AS842DWR is a 10-bit D-type latch manufactured by Rochester Electronics, LLC. It features 3-state outputs designed for driving highly capacitive or low-impedance loads. The device operates within a supply voltage range of 4.5V to 5.5V and supports a working temperature range of 0°C to 70°C. It is housed in a 20-SOIC package.
Feature Summary
- Features 3-state outputs optimized for driving highly capacitive or relatively low-impedance loads.
Applications
- Driving highly capacitive loads
- Driving relatively low-impedance loads
Procurement Notes
Verify the manufacturer designation as Rochester Electronics, LLC, which acts as an authorized continuing source provider. Confirm the specific package type and operating temperature range match system requirements. Ensure the component status aligns with lifecycle expectations for end-of-life extensions.
Selection Notes
Select this component when 10-bit latching functionality with high-drive capability is required. The 3-state output design specifically addresses needs for driving heavy capacitive or low-impedance loads. Verify compatibility with standard 5V logic systems and surface-mount assembly processes using the SOIC package.
Part Context
Rochester Electronics specializes in authorized continuing source solutions for end-of-life semiconductors. This part represents a lifecycle extension product, providing continued availability for components that may have reached obsolescence at original manufacturers. It serves as a bridge for maintaining production in existing designs.
Replacement Considerations
Cross-reference with SN74AS842 variants from other manufacturers if available. Verify pinout and electrical specifications against original datasheets to ensure functional equivalence without modification.
