CD74HC193E

Counter Dividers Overview

The CD74HC193E is a synchronous 4-bit binary up/down counter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports a counting rate of 29 MHz. The device features separate clock inputs for up and down counting, asynchronous master reset, and parallel load capabilities. It is housed in a 16-PDIP package with through-hole mounting and functions across an operating temperature range of -55°C to 125°C.

Counter Dividers Feature Summary

• Synchronous 4-bit binary up/down counting with separate CPU and CPD clock inputs
• Asynchronous master reset and parallel load functionality
• Terminal count outputs (TCU/TCD) that duplicate clock waveforms for cascading

Counter Dividers Applications

• Multistage counter systems requiring synchronous operation
• Digital timing and sequencing circuits
• Frequency division applications using terminal count outputs

Counter Dividers Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to ensure authenticity. Confirm that the 16-PDIP package matches your board layout requirements. Check RoHS compliance status if environmental regulations apply to your assembly process. Ensure supply voltage levels remain within the specified 2 V to 6 V range during operation.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with independent up/down control is required. The HC logic family offers high-speed performance suitable for frequencies up to 29 MHz. Consider the wide operating temperature range for industrial or harsh environment applications. Verify that the through-hole PDIP package aligns with your manufacturing and assembly constraints.

Counter Dividers Part Context

This device belongs to the Texas Instruments 74HC series of high-speed CMOS logic devices. It is functionally compatible with other 74HC193 variants but differs in packaging and suffix designations. The CD prefix indicates commercial grade temperature ratings and standard manufacturing processes defined by the manufacturer.

Counter Dividers Replacement Considerations

Publicly confirmed substitute part numbers include SN74HC193NSR and CD74HC193EE4. Verify pin compatibility and electrical specifications before substitution.
