SN74HCS237PWR

Overview

The SN74HCS237PWR is a high-speed silicon gate CMOS decoder featuring three-to-eight line decoding with latched address inputs and Schmitt-trigger inputs. It operates within a wide supply voltage range of 2 V to 6 V and supports an extended ambient temperature range from –40°C to +125°C. The device includes balanced push-pull outputs capable of driving up to ±7.8 mA at 6 V, ensuring robust signal integrity for memory selection and data routing applications.

Feature Summary

• Schmitt-trigger inputs provide tolerance for slow or noisy input signals
• Latched address inputs retain state when latch enable is high
• Balanced CMOS push-pull outputs support bidirectional current drive

Applications

• Memory device selection with shared data bus
• Reducing required number of outputs for chip select applications
• Routing data in digital systems

Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the TSSOP-16 package configuration. Confirm that the component meets the required RoHS compliance standards for your manufacturing process. Ensure the supply chain source provides valid traceability documentation consistent with Texas Instruments production data requirements.

Selection Notes

Select this component when design requirements include noise immunity via Schmitt triggers and operation across a wide voltage spectrum. Consider the TSSOP-16 package constraints regarding thermal dissipation and board space. Verify that the application logic aligns with the active-low latch enable and strobe functionality defined in the datasheet specifications.

Part Context

This part belongs to the SN74HCS237 family of decoders manufactured by Texas Instruments. It is designed for high-speed CMOS logic applications requiring reliable decoding with address latching capabilities. The PW suffix indicates the specific surface-mount packaging variant available for automated assembly processes.

Replacement Considerations

Consult the official datasheet orderable addendum for verified substitute part numbers. Cross-reference pinouts and electrical characteristics before implementation.
