SN74LS697N

Counter Dividers Overview

The SN74LS697N is a synchronous up/down counter with output registers and multiplexed 3-state outputs manufactured by Texas Instruments. It belongs to the LS logic series, utilizing bipolar technology. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range from 0°C to +70°C. It is housed in a PDIP-16 package for through-hole mounting.

Counter Dividers Feature Summary

• Synchronous up/down counting capability with integrated output registers
• Multiplexed 3-state outputs allowing shared bus connections
• Compatible with standard TTL input levels

Counter Dividers Applications

• Digital counters requiring bidirectional counting
• Bus interface circuits utilizing multiplexed data paths
• Timing control systems with registered outputs

Counter Dividers Procurement Notes

Verify the specific suffix 'N' corresponds to the PDIP-16 package configuration. Confirm RoHS compliance status as legacy LS devices may vary. Ensure the design accommodates the 3-state output requirements and multiplexing logic. Check for obsolescence notices or lifecycle changes from Texas Instruments before finalizing procurement plans.

Counter Dividers Selection Notes

Select this component when synchronous bidirectional counting with registered outputs is required. The multiplexed 3-state feature simplifies bus architecture compared to non-multiplexed alternatives. Verify that the LS logic speed and power consumption meet system constraints. Ensure the PDIP-16 package fits the PCB layout and assembly process.

Counter Dividers Part Context

This part is part of the SN74LS697 family of synchronous counters. It differs from the SN74LS696J, which is a decade counter, by offering up/down functionality and multiplexed outputs. It serves as a specialized digital logic solution for applications needing precise count direction control and flexible output interfacing.

Counter Dividers Replacement Considerations

SN74LS697DW is a pin-compatible alternative in a SOIC package.
