Overview
The DM74AS158N is a multiplexer from the AS Series, featuring four functions with two-line inputs and one inverted output per function. It operates within TTL logic standards and is housed in a PDIP-16 package measuring 0.300 inches. The device supports a maximum operating temperature of 70 °C and contains 16 terminals. It is lead-free and RoHS compliant.
Feature Summary
- Four-function multiplexing capability
- Inverted output configuration
- TTL logic compatibility
Applications
- Data routing in digital systems
- Signal selection circuits
- Multiplexed input processing
Procurement Notes
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm datasheet alignment for pinout and electrical specifications. Ensure packaging integrity matches DIP-16 requirements. Check for RoHS compliance documentation if required by regulatory standards. Validate date codes against current inventory policies to ensure component reliability.
Selection Notes
Select this component for applications requiring four independent 2-to-1 multiplexing functions within a single package. Consider the TTL voltage levels and inverted output polarity when designing interface circuits. The PDIP-16 package is suitable for through-hole mounting on standard PCBs. Verify thermal constraints against the 70 °C maximum operating temperature limit during system integration.
Part Context
This part belongs to the AS series of logic components manufactured by Rochester Electronics. It serves as a discrete multiplexer solution for digital signal processing tasks. The device integrates multiple logical functions into a single integrated circuit, reducing board space compared to discrete implementations. It is designed for general-purpose digital logic applications requiring reliable signal switching.
Replacement Considerations
Direct substitutes include other 74AS158 variants from different manufacturers offering identical pinouts and functionality. Verify electrical characteristics such as propagation delay and power consumption match original specifications. Ensure package dimensions remain compatible with existing footprints. Cross-reference datasheets for any minor differences in recommended operating conditions.
