SN74LV8154NG4

Counter Dividers Overview

The SN74LV8154NG4 is a dual 16-bit binary counter with 3-state output registers from Texas Instruments. It operates on a supply voltage of 2 V to 5.5 V and supports up-counting modes. The device features dedicated clock inputs for each counter, a shared asynchronous clear input, and a storage register that samples counter contents. Outputs are mapped onto an 8-bit bus via byte-select inputs. It utilizes a 20-pin PDIP package.

Counter Dividers Feature Summary

• Dual independent 16-bit counters or single 32-bit configuration
• 3-state output registers with 8-bit data bus mapping
• Partial-power-down support via Ioff circuitry
• Positive-edge triggered clocks with active-low control inputs

Counter Dividers Applications

• Up counters
• Dual up counters
• Chained 32-bit counting systems

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'NG4' against the manufacturer's current orderable addendum. While standard variants like SN74LV8154N exist, confirm if this exact suffix denotes a distinct material type, lead finish, or environmental compliance status. Ensure the component matches the required 20-pin PDIP package dimensions and thermal characteristics specified in the datasheet.

Counter Dividers Selection Notes

Select this component when designing systems requiring two separate 16-bit count events or a cascaded 32-bit counter. It is suitable for applications needing sampled data access through an 8-bit bus interface. Consider its 2-V to 5.5-V operating range and positive-edge triggering requirements. Verify compatibility with system address decoding logic for the four-byte read cycle.

Counter Dividers Part Context

This part belongs to the SN74LV series of logic integrated circuits manufactured by Texas Instruments. It is designed for general-purpose digital counting tasks within low-voltage logic families. The device provides a robust solution for event counting where data sampling and bus interfacing are necessary.

Counter Dividers Replacement Considerations

SN74LV8154NE4 is a confirmed equivalent variant within the same product family offering identical functionality and specifications.
