CD40193BCN

Counter Dividers Overview

The CD40193BCN is a synchronous 4-bit up/down binary counter manufactured by onsemi (formerly Fairchild Semiconductor). It operates within a supply voltage range of 3V to 15V and supports an operating temperature range of -55°C to +125°C. The device features separate clock inputs for counting up and down, with outputs changing on the positive-going transition. It includes asynchronous clear and preset capabilities, along with carry and borrow outputs for cascading. The component is housed in a 16-lead Plastic Dual-In-Line Package (PDIP) with a width of 0.300 inches.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting with dual independent clock inputs for up and down operations
• Asynchronous clear and parallel load functions for immediate state control
• Integrated carry and borrow outputs enabling direct N-bit expansion without external logic
• High noise immunity and low power consumption compatible with TTL standards

Counter Dividers Applications

• Digital frequency counters requiring bidirectional counting
• Timing circuits utilizing presettable binary sequences
• Cascaded multi-stage digital systems for extended bit-width applications
• Industrial control logic involving pulse accumulation or subtraction

Counter Dividers Procurement Notes

Verify that the ordering suffix 'N' corresponds to the 16-lead PDIP package as specified in the datasheet. Confirm RoHS compliance status through official manufacturer documentation, as historical data indicates variations. Ensure the supplier provides valid traceability for the onsemi/Fairchild manufacturing origin. Check for any specific handling requirements regarding static discharge protection during storage and assembly.

Counter Dividers Selection Notes

Select this component when a synchronous binary counter with independent up/down clocks is required. It is suitable for designs needing wide voltage operation from 3V to 15V. Consider the PDIP package for through-hole mounting needs. Verify that the maximum count frequency at the target supply voltage meets the system timing requirements. Ensure compatibility with existing CMOS logic families in the design.

Counter Dividers Part Context

The CD40193BC belongs to the 4000 series of CMOS integrated circuits. It is functionally similar to the CD40192 but counts in binary rather than BCD. The 'BC' designation typically refers to the commercial grade variant with specific electrical characteristics. This part is part of a broader family of counters and shift registers designed for general-purpose digital logic applications.

Counter Dividers Replacement Considerations

Equivalent parts include the MM74C193 and other CD40193 variants from different manufacturers such as Texas Instruments or National Semiconductor. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement part supports the same 16-pin DIP package if physical constraints are critical.
