SN74F157ANG4

Overview

The SN74F157ANG4 is a quad 2-line to 1-line data selector/multiplexer from the Texas Instruments 74F series. It features four independent multiplexers in a single package, providing high-speed data routing capabilities. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports through-hole mounting in a standard 16-pin DIP package. It is designed for applications requiring fast propagation delays and robust logic performance in digital systems.

Feature Summary

• Contains four independent 2-to-1 multiplexers for parallel data selection
• Utilizes high-speed 74F logic technology for rapid signal processing
• Provides true outputs without inversion for direct logic interfacing

Applications

• Data routing in digital communication systems
• Address decoding and bus switching applications
• General-purpose logic circuit design requiring multiple selectors

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free manufacturing status as per Texas Instruments documentation. Confirm the package type matches the required PCB footprint for through-hole assembly. Ensure the operating temperature range aligns with the system environment specifications before finalizing procurement decisions.

Selection Notes

Select this component when high-speed switching is required compared to standard 74LS series devices. Consider the 74F series characteristics for faster propagation delays. Evaluate the power consumption requirements against the available thermal management solutions in the target application design.

Part Context

This part belongs to the broader 74F family of high-speed TTL logic devices. The SN74F157A variant serves as the base model for this quad multiplexer configuration. The G4 suffix typically denotes environmental compliance modifications while maintaining identical electrical functionality to the standard SN74F157AN device.

Replacement Considerations

The SN74F157AN is the primary equivalent part number offering identical pinout and electrical specifications. Verify that any substitute maintains the same 74F speed grade and 5V operation requirements.
