74HC6323AD,112

Counter Dividers Overview

The Nexperia 74HC6323AD,112 is a programmable ripple counter with an integrated oscillator and 3-state output buffer. It operates in SO8 packages within -40 °C to +125 °C. Supply voltage ranges from 2.0 V to 6.0 V for HC variants. The device supports divide-by-1, 2, 4, or 8 modes via select inputs S1 and S2. It features on-chip capacitors for third overtone crystal applications up to 50 MHz. An asynchronous master reset (MR) stops oscillation and enables 3-state outputs.

Counter Dividers Feature Summary

• Integrated Pierce-type oscillator supporting fundamental and third overtone quartz crystals
• Programmable 3-stage binary ripple counter with selectable divide ratios
• 3-state output buffer controlled by master reset input
• Built-in 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 the specific ordering suffix matches the required package type and temperature range. Confirm that the 'AD' designation corresponds to the SO8 plastic small outline package. Ensure compatibility with system supply voltages and logic levels before integration. Cross-reference the datasheet revision date to confirm current manufacturing status.

Counter Dividers Selection Notes

Select this component when a combined clock source and frequency division function is required in a single package. The HC variant suits CMOS logic families, while HCT interfaces with TTL levels. Verify that the application requires the specific divide-by options provided. Consider the internal capacitance values if designing for third overtone crystals without external components.

Counter Dividers Part Context

This part belongs to the 74HC/HCT6323A family of programmable ripple counters with oscillators. It shares functional characteristics with other members of the series but differs in package configuration and electrical specifications defined by the HC logic family standards. The device integrates oscillator and counting functions typically requiring multiple discrete components.

Counter Dividers Replacement Considerations

Direct substitutes include the 74HCT6323AD,112 for TTL-compatible logic levels. Other 74HC6323 variants may be compatible if package and temperature ratings align. Verify pinout and electrical parameters against the target design requirements before substitution.
