74HC193D,653

Counter Dividers Overview

The Nexperia 74HC193D,653 is a synchronous reversible 4-bit binary counter housed in a 16-lead SO plastic small outline package (SOT109-1). It operates on a wide supply voltage range from 2.0 V to 6.0 V with CMOS low power dissipation and high noise immunity. The device features separate up/down clock inputs (CPU and CPD) for independent control of counting direction. Outputs change state synchronously with the LOW-to-HIGH transition of either clock input. It includes asynchronous parallel load and master reset capabilities.

Counter Dividers Feature Summary

• Supports synchronous reversible 4-bit binary counting using separate CPU and CPD clock inputs
• Features asynchronous parallel load and asynchronous master reset functions
• Includes terminal count outputs (TCU and TCD) that duplicate clock waveforms for multistage expansion

Counter Dividers Applications

• Multistage counters utilizing cascaded terminal count outputs
• Systems requiring presettable synchronous binary counting
• Applications needing independent up and down clock control

Counter Dividers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and temperature range. Confirm RoHS compliance status and ESD protection ratings as specified in the latest product data sheet revision before finalizing procurement specifications.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit up/down counter with separate clock inputs is required. Ensure the operating voltage falls within the 2.0 V to 6.0 V range. Consider the asynchronous nature of the parallel load and reset inputs when designing timing sequences relative to the synchronous clock transitions.

Counter Dividers Part Context

This part belongs to the 74HC193 family of presettable synchronous 4-bit binary up/down counters manufactured by Nexperia. It is designed for general-purpose digital logic applications requiring reliable binary counting with flexible loading and resetting options across a standard industrial temperature range.

Counter Dividers Replacement Considerations

Check for direct pin-compatible alternatives within the same logic family or other manufacturers offering identical functional specifications and package dimensions.
