SN74HCS153PWR

Overview

The SN74HCS153PWR is a dual 4-to-1 multiplexer with Schmitt-trigger inputs in a 16-pin TSSOP package. It operates from 2 V to 6 V, supporting an extended temperature range of –40°C to +125°C. The device features balanced CMOS push-pull outputs capable of ±7.8 mA drive at 6 V. Typical supply current is 100 nA, and input leakage is ±100 nA. Propagation delay ranges from 6 ns to 45 ns depending on voltage and temperature.

Feature Summary

• Schmitt-trigger inputs provide high noise immunity and tolerance for slow signal transitions.
• Dual independent channels share common address select inputs for synchronized data routing.
• Balanced CMOS push-pull outputs ensure symmetric sourcing and sinking capabilities.

Applications

• Data selection
• Multiplexing

Procurement Notes

Verify the specific ordering suffix 'PW' confirms the TSSOP-16 package variant. Confirm RoHS compliance and lead finish details via the manufacturer's orderable addendum. Ensure the application environment stays within the specified –40°C to +125°C operating temperature range to maintain guaranteed electrical characteristics.

Selection Notes

Select this component when noisy environments require Schmitt-trigger input hysteresis. Choose this part over standard HC variants if slow input signals are present. Verify that the required output drive current does not exceed the ±7.8 mA limit at the target supply voltage.

Part Context

This device belongs to the Texas Instruments HCS logic family, which integrates Schmitt-trigger functionality into standard HCMOS architectures. It serves as a direct functional upgrade to the SN74HC153, offering improved noise rejection while maintaining compatible pinouts and logical operations for system upgrades.
