SN74HCS153QPWRQ1

Overview

The SN74HCS153QPWRQ1 is an automotive-grade dual 4-to-1 multiplexer featuring Schmitt-trigger inputs. It operates within a supply voltage range of 2 V to 6 V and supports an ambient temperature range from -40°C to +125°C. The device provides balanced CMOS push-pull outputs with ±7.8 mA drive capability at 6 V. Propagation delay ranges from 6 ns to 45 ns depending on voltage and temperature. Input leakage current is typically ±100 nA, and supply current is typically 100 nA.

Feature Summary

• Dual 4-to-1 data selection with shared address inputs
• Schmitt-trigger inputs for noise rejection
• Active-low strobe control for each channel
• Wettable flank package option for improved inspection

Applications

• Data selection
• Multiplexing

Procurement Notes

Verify the specific package suffix (PW, D, or WBQB) matches the required footprint. Confirm AEC-Q100 qualification requirements are met for the target automotive application. Ensure input signals remain within absolute maximum ratings to prevent damage from overvoltage or excessive clamp currents.

Selection Notes

Select this component for applications requiring dual independent multiplexing channels controlled by common address lines. The Schmitt-trigger inputs make it suitable for noisy environments or slow signal transitions. Verify that the output drive current requirements do not exceed the specified limits for the chosen supply voltage.
