SN74AHC158DGVR

Signal Switches, Multiplexers, Decoders Overview

The SN74AHC158DGVR is a quadruple 2-line to 1-line data selector/multiplexer from the Texas Instruments AHC logic family. 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 routes a 4-bit word from one of two sources based on the address selection. It is housed in a TVSOP-16 package, supports an operating temperature range of -40°C to +85°C, and includes high ESD protection capabilities.

Signal Switches, Multiplexers, Decoders Feature Summary

• Features a common strobe input for synchronized control of all four multiplexers
• Provides inverted data outputs when enabled by the strobe signal
• Supports wide supply voltage operation from 2 V to 5.5 V
• Includes robust ESD protection exceeding standard human-body and machine model ratings

Signal Switches, Multiplexers, Decoders Applications

• Data routing in digital systems requiring multiple source selection
• Address decoding circuits utilizing the quadruple configuration
• Signal path switching controlled by a global enable strobe
• Logic interface modules operating across varying voltage domains

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'DGVR' corresponds to the TVSOP-16 tape and reel packaging format. Confirm the component status as active production or obsolete through official Texas Instruments channels before finalizing procurement plans. Ensure compliance with RoHS directives and check for any specific material type designations relevant to the manufacturing batch.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a quad multiplexer with inverted outputs and a shared strobe control is required. The AHC series offers CMOS performance with TTL-compatible inputs. Consider the TVSOP-16 package constraints regarding thermal impedance and board space. Verify that the 2-V to 5.5-V operating range aligns with the target system power supply specifications.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN54/74AHC158 family of quadruple 2-line to 1-line data selectors. The 'SN74' prefix indicates commercial grade availability, while 'AHC' denotes advanced high-speed CMOS technology. The 'DGVR' suffix specifies the surface-mount TVSOP package and tape-and-reel shipping method, distinguishing it from tube-packaged variants like the SN74AHC158D.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct pin-compatible alternatives within the same family include SN74AHC158DR (SOIC package) and SN74AHC158DBR (SSOP package). Cross-family replacements such as the SN74HC158 offer similar functionality but may differ in speed and drive characteristics. Verify electrical parameters against the original datasheet requirements.
