HCF40193BEY

Counter Dividers Overview

The HCF40193BEY is a synchronous presettable up/down counter manufactured by STMicroelectronics in the HCF series. It features dual clock inputs for independent up and down counting operations, along with a reset function. The device supports binary counting with four output lines and operates within a supply voltage range of 3 V to 20 V. It is designed for through-hole mounting in a 16-DIP package and exhibits a count rate capability of 11 MHz at positive edge triggering.

Counter Dividers Feature Summary

• Synchronous presettable up/down counting functionality with dual clock inputs
• Integrated reset capability for immediate state initialization
• Compatible with standard logic families for shift register applications

Counter Dividers Applications

• Binary counter circuits requiring preset values
• Shift register configurations via feedback connections
• Toggle mode implementations using Q output to data input

Counter Dividers Procurement Notes

Verify the specific suffix 'BEY' against official STMicroelectronics documentation to confirm pinout and electrical characteristics. Ensure compatibility with the required operating temperature range of -55°C to specified maximums. Confirm that the 16-DIP through-hole package meets your PCB layout constraints before finalizing procurement decisions.

Counter Dividers Selection Notes

Select this component when synchronous operation with separate up/down clocks is required. The wide supply voltage range allows flexibility in power design. Consider the 11 MHz count rate limit for high-speed applications. Verify that the presettable feature aligns with system initialization requirements compared to non-presettable alternatives.

Counter Dividers Part Context

This part belongs to the HCF40193 family of CMOS counters. It shares functional similarities with other presettable counters but offers specific timing and voltage characteristics defined by the HCF technology. The device is distinct from BCD variants like the HCF40192B, focusing on binary counting operations.

Counter Dividers Replacement Considerations

Check for direct substitutes such as the HCF40192B if BCD decoding is acceptable. Verify pin compatibility with other 40193-series devices from different manufacturers. Ensure replacement parts maintain the same synchronous operation and voltage specifications.
