• Ensures performance compliance with original OEM specifications
• Supports standard TTL/H/L series logic input requirements

Applications

• Timing pulse generation circuits
• Fixed-length time delay applications
• Frequency division systems

Procurement Notes

Verify the specific suffix 'G' indicates lead-free packaging status as documented in official datasheets. Confirm that the 16-PDIP package dimensions match MS-001 standards. Ensure the component meets the specified -40°C to 85°C operating temperature range for your application environment. Cross-reference the part number with Rochester Electronics documentation to confirm authenticity and original OEM specification compliance.

Selection Notes

Select this component when a reliable monostable multivibrator with 22 ns propagation delay is required. The 2 V to 6 V supply range offers flexibility for various logic levels. The through-hole PDIP package is suitable for prototyping or legacy board designs. Verify that the 5.2 mA output current capability meets the load requirements of the connected circuitry.

Part Context

Rochester Electronics specializes in sourcing and distributing obsolete and hard-to-find semiconductor components. They guarantee that their products meet the original manufacturer's specifications. This part belongs to the HC (High-speed CMOS) logic family, offering compatibility with standard digital logic interfaces while providing robust performance characteristics.

Replacement Considerations

Consult official Rochester Electronics documentation for verified substitute part numbers. Do not assume functional equivalence with other monostable multivibrators without verifying pinout and electrical parameter alignment.
