SN74AHCT158DRG4

Signal Switches, Multiplexers, Decoders Overview

The SN74AHCT158DRG4 is a quadruple 2-line to 1-line data selector/multiplexer designed for 4.5-V to 5.5-V VCC operation. It features TTL-voltage compatible inputs and provides inverted data outputs. The device includes a common strobe (G) input that forces all outputs high when active, or routes a selected 4-bit word from two sources to the four outputs when inactive. It operates within an ambient temperature range of -40°C to 85°C.

Signal Switches, Multiplexers, Decoders Feature Summary

• TTL-voltage compatible inputs ensure seamless integration with standard logic families.
• Common strobe input controls output states, forcing them high when activated.
• Provides inverted data routing from dual sources to four independent outputs.

Signal Switches, Multiplexers, Decoders FAQ

What is the function of the common strobe input?

When the strobe input is high, all outputs are forced high. When low, the device selects data from the A or B inputs based on the select line.

Are the inputs compatible with TTL voltage levels?

Yes, the SN74AHCT158 devices feature TTL-voltage compatible inputs.
