74HCT6323AD/C4J

Counter Dividers Overview

The Nexperia 74HCT6323AD/C4J is a programmable ripple counter with an integrated oscillator and 3-state output buffer. It features an overriding asynchronous master reset (MR) and two select inputs (S1, S2) for divide-by-1, 2, 4, or 8 modes. The oscillator supports fundamental or third overtone quartz crystal operation up to 50 MHz at VCC = 5 V ± 10%. On-chip capacitors minimize external components for third overtone applications. The device operates within a supply voltage range of 4.5 V to 5.5 V and functions across temperatures from -40 °C to +125 °C.

Counter Dividers Feature Summary

• Integrated Pierce-type oscillator suitable for fundamental and third overtone quartz crystals
• Programmable 3-stage binary ripple counter with selectable division ratios
• 3-state output buffer controlled by the master reset input
• Internal pull-up resistors on control inputs to ensure inactive states when floating

Counter Dividers Applications

• Control counters
• Timers
• Frequency dividers
• Time-delay circuits
• Compact Integrated Oscillator (CIO)

Counter Dividers Procurement Notes

Verify that the specific suffix /C4J corresponds to the standard SO8 package (SOT96-1) as defined in the official ordering information table. Confirm RoHS compliance and REACH status through manufacturer documentation. Ensure the procurement channel provides valid traceability for the Nexperia USA Inc. manufacturing origin.

Counter Dividers Selection Notes

Select this component for designs requiring a combined clock source and frequency divider in a single package. The HCT logic family ensures TTL-compatible input levels. Verify that the application utilizes the internal pull-ups correctly if MR, S1, or S2 are left unconnected to achieve default high states.

Counter Dividers Part Context

This part belongs to the 74HCT6323A series, which integrates a programmable counter with a crystal oscillator. It is designed to reduce component count in timing circuits by combining oscillation, counting, and buffering functions. The device is specified for industrial temperature ranges and offers ESD protection exceeding 2000 V via the Human Body Model.

Counter Dividers Replacement Considerations

Direct replacements include the 74HC6323AD variant, noting differences in input switching levels between HC and HCT families. Other compatible parts must support the same 3-state output functionality and programmable divide-by modes.
