CD74HC192PW

Counter Dividers Overview

The CD74HC192PW is a high-speed CMOS logic presettable synchronous BCD decade up/down counter with asynchronous reset, manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports bidirectional counting via separate up and down clock inputs. The device features parallel load capability for presetting data and includes TCO (Terminal Count Output) pins for both up and down counting directions. Packaged in a 16-TSSOP surface-mount format, it functions reliably across an extended temperature range from -55°C to +125°C.

Counter Dividers Feature Summary

• Synchronous BCD decade counting with independent up and down clock inputs
• Asynchronous reset and parallel load functionality for immediate data initialization
• Terminal count outputs facilitate cascading multiple counters without external logic

Counter Dividers Applications

• Digital frequency division circuits
• Time-base generation in digital clocks
• Pulse sequence generation systems

Counter Dividers Procurement Notes

Verify the package type matches the required 16-TSSOP footprint during integration. Confirm that the operating voltage aligns with the specified 2 V to 6 V range for the target application environment. Ensure thermal management accounts for the extended temperature rating of -55°C to +125°C if used in harsh conditions.

Counter Dividers Selection Notes

Select this component when a synchronous BCD decade counter with separate direction control is required. It is suitable for designs needing precise timing control via distinct clock inputs rather than a single clock with a direction pin. Consider the TSSOP package for space-constrained surface-mount applications.

Counter Dividers Part Context

This part belongs to the Texas Instruments 74HC series of high-speed CMOS logic devices. It is functionally compatible with other industry-standard BCD decade counters but offers specific Texas Instruments manufacturing characteristics. The 'PW' suffix denotes the 16-lead Thin Shrink Small Outline Package (TSSOP).

Counter Dividers Replacement Considerations

Check for equivalent parts such as the CD74HC192PWR or CD74HC192EE4, ensuring package compatibility and electrical specifications match the design requirements.
