SN74F151BNG4

Overview

The SN74F151BNG4 is an 8-Line to 1-Line Data Selector/Multiplexer from Texas Instruments' SN74F series. It features a 16-pin PDIP package and operates within a supply voltage range of 4.5 V to 5.5 V. The component exhibits a propagation delay of 9.5 ns and functions reliably across an operating temperature range of 0°C to +70°C. It provides one circuit with eight inputs and a single output, designed for high-speed digital signal routing applications in standard logic environments.

Feature Summary

• Provides 8-to-1 data selection capability using three address lines
• Features fast switching speeds suitable for high-frequency digital systems
• Includes active-low enable input for precise control over data flow

Applications

• Data routing in digital communication systems
• Address decoding in microprocessor-based designs
• Waveform generation circuits

Procurement Notes

Verify the specific suffix 'NG4' against current manufacturer documentation to confirm RoHS compliance status and lead-free characteristics. Confirm availability as this component may be subject to discontinuation or lifecycle changes. Ensure the 16-pin DIP package matches your PCB footprint requirements before procurement.

Selection Notes

Select this component when high-speed multiplexing is required within a 5V logic system. Compare its 9.5 ns propagation delay against HC series alternatives if speed is critical. Ensure the through-hole PDIP package aligns with assembly capabilities. Verify that the 4.5V to 5.5V operating range suits the target power supply infrastructure.

Part Context

This part belongs to the SN74F series, known for high-speed performance compared to standard TTL. It serves as a functional equivalent to other 8:1 multiplexers in the 74xx family but offers faster switching characteristics. The device is widely used in legacy and industrial digital designs requiring reliable data selection.

Replacement Considerations

Consider SN74F251BN for applications requiring a tri-state output. SN74HC151DG4 offers similar functionality with lower power consumption and wider voltage range but slower speed. Verify pin compatibility and electrical specifications before substitution.
