CD74HCT193E

Counter Dividers Overview

The CD74HCT193E is a synchronous 4-bit binary up/down counter manufactured by Harris Corporation. It operates within a supply voltage range of 4.5V to 5.5V and supports a count rate of 22 MHz. The device features independent up and down clock inputs for bidirectional counting control. It is housed in a 16-pin DIP package with an operating temperature range of -55°C to 125°C.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting architecture
• Independent up and down clock inputs for bidirectional operation
• High-speed performance with 22 MHz count rate capability

Counter Dividers Applications

• Digital frequency division circuits
• Time-base generation systems
• Position control logic in industrial automation

Counter Dividers Procurement Notes

Verify RoHS compliance status as the component may not meet current environmental standards. Confirm package type matches design requirements, as variations exist between DIP and surface mount options. Check manufacturer documentation for specific handling instructions regarding moisture sensitivity level 3. Ensure supply voltage specifications align with system power rails before integration.

Counter Dividers Selection Notes

Select this component for applications requiring precise synchronous binary counting with separate control for increment and decrement operations. The wide operating temperature range makes it suitable for harsh environments. Consider the 16-pin DIP package for prototyping or through-hole manufacturing processes where surface mount technology is not feasible.

Counter Dividers Part Context

This part belongs to the Harris Semiconductor 74HCT logic family, designed for high-speed CMOS applications compatible with TTL inputs. The CD74HCT193 series provides reliable binary counting functionality. It is distinct from non-synchronous counters and offers dedicated carry/borrow outputs for cascading multiple units to create larger modulus counters.

Counter Dividers Replacement Considerations

Compatible substitutes include SN74HCT193N and MC74HC193P. Verify pin compatibility and electrical characteristics against original datasheets before substitution.
