SN74AHCT158D

Signal Switches, Multiplexers, Decoders Overview

The SN74AHCT158D is a quadruple 2-line to 1-line data selector/multiplexer from the AHCT logic family, manufactured by Texas Instruments. Designed for 4.5-V to 5.5-V VCC operation, it features TTL-voltage compatible inputs and inverted outputs. The device integrates four independent multiplexers with a common strobe (G) input that disables all outputs when high. It operates within an ambient temperature range of -40°C to +85°C and utilizes a 16-pin SOIC package.

Signal Switches, Multiplexers, Decoders FAQ

What is the function of the G input?

When the G input is high, all outputs are disabled and held high. When low, the selected data inputs are routed to the outputs.

Are the outputs inverted?

Yes, the SN74AHCT158D provides inverted data at its outputs relative to the selected inputs.
