CY74FCT191ATSOC

Counter Dividers Overview

The CY74FCT191ATSOC is a synchronous, presettable 4-bit up/down binary counter manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range from -40°C to +85°C. The device is housed in a 16-pin SOIC surface-mount package and belongs to the 74FCT logic series.

Counter Dividers Feature Summary

• Synchronous counting architecture with simultaneous output updates on clock edges
• Bidirectional counting capability supporting both up and down sequences
• Presettable data input allowing direct loading of initial count values

Counter Dividers Applications

• Digital timing and sequencing circuits
• Frequency division networks
• Position control systems requiring bidirectional tracking

Counter Dividers Procurement Notes

Verify the specific suffix 'SO' indicates the SOIC-16 package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified 4.75 V to 5.25 V power supply requirements for reliable operation.

Counter Dividers Selection Notes

Select this component when a compact, synchronous 4-bit counter with bidirectional functionality is required. The SOIC-16 package suits space-constrained surface-mount designs. Verify that the 74FCT logic family characteristics align with the system's interface voltage levels and speed requirements.
