SN74AHC158DBR

Signal Switches, Multiplexers, Decoders Overview

The SN74AHC158DBR is a quadruple 2-line to 1-line data selector/multiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features a common strobe (G) input that controls output states. The device provides inverted data outputs and selects a 4-bit word from two sources when the strobe is low. It is housed in a 16-pin SSOP package with an operating temperature range of -40°C to 85°C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'DBR' corresponds to the SSOP-16 tape and reel packaging configuration. Confirm the active production status and RoHS compliance details directly with Texas Instruments or authorized distributors, as product availability and specifications are subject to change without notice.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a quadruple multiplexer with inverted outputs is required. Ensure the application voltage falls within the 2 V to 5.5 V range. Consider the SSOP-16 package dimensions for PCB layout compatibility. Verify that the common strobe functionality aligns with the system's control logic requirements.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN74AHC158 family of quadruple 2-line to 1-line data selectors. It is designed for CMOS technology and offers latch-up performance exceeding 250 mA per JESD 17. The device is intended for general-purpose digital applications requiring reliable signal selection and inversion.

Signal Switches, Multiplexers, Decoders FAQ

What is the function of the common strobe (G) input?

When the strobe is high, all outputs are high. When the strobe is low, a 4-bit word is selected from one of two sources and routed to the four outputs.

Does the SN74AHC158DBR provide non-inverted or inverted outputs?

The device provides inverted data outputs.
