SN74HC191DRG4

Counter Dividers Overview

The SN74HC191DRG4 is a synchronous 4-bit up/down binary counter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -40°C to +85°C. The device features asynchronous reset, positive-edge triggering, and parallel load capabilities. It is housed in a 16-SOIC surface-mount package.

Counter Dividers Feature Summary

• Synchronous 4-bit up/down binary counting functionality
• Asynchronous reset and parallel load inputs for flexible control
• Positive-edge clock triggering mechanism

Counter Dividers Applications

• Digital frequency division circuits
• Position control systems requiring bidirectional counting
• Timing sequence generation logic

Counter Dividers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free packaging compliance with RoHS standards as per Texas Instruments documentation. Confirm the SOIC-16 package dimensions match your PCB footprint requirements. Ensure the operating environment stays within the specified -40°C to +85°C temperature range for reliable performance.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with bidirectional capability is required. It is suitable for designs needing parallel loading and asynchronous reset functions. Consider the HC logic family characteristics regarding speed and power consumption relative to other 74-series options.

Counter Dividers Part Context

This part belongs to the SN74HC191 series of high-speed CMOS logic devices. It serves as a digital counter solution within Texas Instruments' extensive portfolio of logic integrated circuits. The DRG4 designation specifies the tape-and-reel packaging format and lead-free construction.

Counter Dividers Replacement Considerations

SN74HC191DR is the non-G4 variant with identical electrical specifications but potentially different packaging compliance details.
