CY74FCT191CTSOC

Counter Dividers Overview

The CY74FCT191CTSOC is a synchronous four-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 bidirectional counting sequences controlled by an Up/Down input. The device features a presettable data capability, allowing parallel loading of data into the counter registers. It is housed in a 16-pin SOIC surface-mount package and is rated for industrial operating temperatures from -40°C to +85°C.

Counter Dividers Feature Summary

• Synchronous four-bit binary counting architecture with dedicated up/down control logic
• Parallel load functionality enabling direct presetting of counter values
• Industrial temperature range support for reliable operation in demanding environments

Counter Dividers Applications

• Digital timing and sequencing circuits requiring precise count tracking
• Frequency division networks in clock distribution systems
• Address generation modules in memory interfacing applications

Counter Dividers Procurement Notes

Verify the specific suffix 'CSOC' against the official datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm that the 16-SOIC footprint matches your PCB design constraints before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when a synchronous four-bit counter with parallel load capability is required. The FCT logic family offers CMOS compatibility with TTL-level inputs. Consider the 16-SOIC package size for space-constrained designs. Verify that the 5V supply voltage aligns with the system power rails.

Counter Dividers Part Context

This part belongs to the CY74FCT191T series of high-speed CMOS logic devices. The series provides performance comparable to LS-TTL but with lower power consumption. The CY74FCT191 variant specifically addresses applications needing compact synchronous counting solutions with flexible data loading options.

Counter Dividers Replacement Considerations

Check for CY74FCT191ATSOCT as a potential alternative if different packaging or lead-free status is required. Verify pinout compatibility and electrical characteristics before substitution.
