SN74AHCT158DE4

Signal Switches, Multiplexers, Decoders Overview

The SN74AHCT158DE4 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 when inactive. It offers ESD protection exceeding JESD 22 standards and latch-up performance exceeding 250 mA per JESD 17.

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.
