Overview
The SN74180N is a 9-bit odd/even parity generator and checker integrated circuit manufactured by Texas Instruments. It belongs to the standard TTL logic family and is housed in a PDIP-14 package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical specifications include a propagation delay time of 68 ns.
Feature Summary
- Performs 9-bit odd or even parity generation and checking functions
- Provides complementary outputs for flexible logic integration
- Compatible with standard TTL logic families
Applications
- Digital logic circuits requiring parity verification
- Data transmission systems for error detection
- Consumer electronics utilizing standard TTL interfaces
Procurement Notes
Verify the specific manufacturer datasheet to confirm pinout compatibility and electrical characteristics against original design requirements. Ensure the PDIP-14 package matches the target PCB footprint. Confirm that the operating temperature range meets the application's environmental conditions before finalizing procurement decisions.
Selection Notes
Select this component when a dedicated 9-bit parity solution is required within a standard TTL environment. Consider the 68 ns propagation delay for timing constraints. Verify that the 5V supply voltage aligns with the system power rails. Evaluate the PDIP-14 through-hole package suitability against available surface-mount alternatives if space is limited.
Part Context
This part is part of the SN74180 series, designed specifically for parity operations. It serves as a fundamental building block in digital systems where data integrity checks are necessary. The device simplifies circuit design by integrating both generator and checker functionalities into a single package.
Replacement Considerations
Check for direct equivalents from other manufacturers offering identical pinouts and electrical specs. Verify functional compatibility with existing TTL logic levels. Ensure substitute packages match the physical dimensions and mounting requirements of the current design.
