N74F193D,623

Counter Dividers Overview

The N74F193D,623 is a synchronous reversible 4-bit binary counter manufactured by NXP USA Inc. It features separate clock inputs for up and down counting operations. The device supports asynchronous parallel load and master reset functions. It operates within a supply voltage range of 4.5V to 5.5V and an ambient temperature range of 0°C to +70°C. The maximum clock frequency is 125MHz at typical conditions. Propagation delays from clock to output range from 2.5ns to 13.0ns depending on direction and load. Total supply current is typically 32mA.

Counter Dividers Feature Summary

• Synchronous reversible 4-bit counting with separate CPU and CPD clock inputs
• Asynchronous parallel load capability for presetting data values
• Asynchronous master reset (clear) function to set outputs low
• Cascadable design without requiring external logic components

Counter Dividers Applications

• Multistage counter systems utilizing terminal count outputs
• Digital systems requiring presettable binary counters

Counter Dividers Procurement Notes

Verify the specific package type required, as the D suffix indicates a 16-pin plastic SOIC package. Confirm that the commercial temperature range of 0°C to +70°C meets system requirements. Ensure supply voltage stability within the 4.5V to 5.5V specification during operation. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans.

Counter Dividers Selection Notes

Select this component when separate up and down clock signals are available in the design. The device is suitable for applications requiring fast switching speeds up to 125MHz. Consider the 16-pin SO package constraints for PCB layout. Verify fan-out capabilities against connected loads, noting the standard FAST logic loading characteristics defined in the datasheet.

Counter Dividers Part Context

This part belongs to the 74F series of high-speed CMOS logic devices produced by Philips Semiconductors, now NXP. The 74F193 is a standard industry-compatible 4-bit up/down counter. It provides a robust solution for bidirectional counting tasks where precise timing control via separate clocks is necessary. The device utilizes master-slave JK flip-flops internally.

Counter Dividers Replacement Considerations

Compatible substitutes include other 74F193 variants from different manufacturers that maintain pin compatibility and electrical specifications. Verify that any replacement supports the same asynchronous load and reset functionalities. Ensure the alternative device meets the 125MHz maximum frequency requirement and operates within the specified voltage and temperature ranges.
