SN74AHCT158PW

Signal Switches, Multiplexers, Decoders Overview

The SN74AHCT158PW is a quadruple 2-line to 1-line data selector/multiplexer designed for 4.5-V to 5.5-V VCC operation. It features a common strobe (G) input that controls output states and an A/B select input for routing data. The device provides inverted outputs and includes TTL-voltage compatible inputs. It operates within a temperature range of -40°C to +85°C and utilizes a TSSOP-16 package.

Signal Switches, Multiplexers, Decoders Feature Summary

• Features a common strobe input to control all four multiplexers simultaneously
• Provides inverted data outputs for selected channels
• Inputs are TTL-voltage compatible for direct interfacing with TTL logic

Signal Switches, Multiplexers, Decoders Applications

• Data routing in digital systems
• Signal selection circuits
• Multiplexing applications requiring TTL compatibility

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel quantity, as the PW suffix indicates a tube package while PWR indicates tape and reel. Confirm RoHS compliance status and ensure the operating temperature range meets system requirements. Check for any obsolescence notices or lifecycle changes before finalizing procurement plans.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a quadruple 2-to-1 multiplexer with inverted outputs is required. Ensure the supply voltage remains between 4.5 V and 5.5 V. Verify that the TTL-compatible input levels match the driving logic family. Consider the TSSOP-16 package constraints for PCB layout and thermal management.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN74AHCT158 series of quadruple 2-line to 1-line data selectors/multiplexers. It is part of Texas Instruments' AHCT logic family, which combines high-speed CMOS performance with TTL-compatible inputs. The PW suffix denotes the TSSOP package variant.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check for equivalent parts from other manufacturers offering similar functionality and pinout compatibility. Verify electrical specifications such as propagation delay and output current capabilities. Ensure the replacement supports the same operating voltage and temperature range.
