CD74HC193MT

Counter Dividers Overview

The CD74HC193MT is a high-speed CMOS logic device manufactured by Texas Instruments, belonging to the 74HC series. It functions as a single-element, 4-bit synchronous binary up/down counter housed in a 16-SOIC surface-mount package. The component operates within a supply voltage range of 2 V to 6 V and supports an asynchronous master reset input for immediate clearing. It features separate clock inputs for counting up and down, allowing independent control of count direction. The outputs change state synchronously with the low-to-high transition of the respective clock inputs.

Counter Dividers Feature Summary

• Synchronous 4-bit binary up/down counting capability with separate clock inputs
• Asynchronous parallel load function for direct data entry into outputs
• Asynchronous master reset input to clear all outputs to a low state
• Terminal count outputs that duplicate clock waveforms for cascading

Counter Dividers Applications

• Digital frequency counters requiring precise up/down measurement
• Position control systems utilizing incremental encoders
• Timing circuits needing programmable preset values
• Cascaded multi-stage digital counters for extended bit ranges

Counter Dividers Procurement Notes

Verify the specific suffix 'MT' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and temperature rating. Ensure the ordering part number matches the required package variant, as suffixes often denote specific shipping or environmental qualifications distinct from the base functional model.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with independent up/down control is required in a surface-mount design. It is suitable for applications operating between 2 V and 6 V where separate clock lines simplify timing logic compared to single-clock reversible counters. Verify that the SOIC-16 footprint aligns with the PCB layout constraints.

Counter Dividers Part Context

This device is part of the Texas Instruments 74HC family of high-speed CMOS logic ICs. It shares functional similarities with other 74HC193 variants but is distinguished by its specific surface-mount packaging designation. The component serves as a fundamental building block for sequential logic designs requiring reliable binary counting operations.

Counter Dividers Replacement Considerations

Compatible substitutes include SN74HC193DR and SN74HC193NSR from Texas Instruments, which offer identical logical functionality. Other manufacturers producing standard 74HC193 devices may also serve as equivalents provided the pinout and electrical specifications match the original requirements.
