SN74LS697DW

Counter Dividers Overview

The SN74LS697DW is a synchronous up/down counter with output registers manufactured by Texas Instruments. It features multiplexed 3-state outputs and operates within a supply voltage range of 4.75 V to 5.25 V. The device utilizes the LS logic series and is housed in an SOIC-20 package. It supports bidirectional counting operations controlled by dedicated inputs, providing registered data output through its tri-state buffers for bus interfacing applications.

Counter Dividers Feature Summary

• Synchronous up/down counting capability with integrated output registers
• Multiplexed 3-state outputs for efficient bus sharing
• Compatible with standard TTL input levels

Counter Dividers Applications

• Bidirectional data buffering in digital systems
• Address generation in memory systems
• Position control circuits requiring direction awareness

Counter Dividers Procurement Notes

Verify component authenticity due to end-of-life status. Confirm package integrity and pin alignment against original specifications. Review manufacturer documentation for any obsolescence notices or recommended alternative part numbers before finalizing procurement decisions.

Counter Dividers Selection Notes

Select this component when synchronous bidirectional counting with registered outputs is required. Ensure system voltage matches the specified 5V tolerance. Consider the SOIC-20 footprint constraints during PCB layout design. Verify compatibility with existing logic families driving the count and direction inputs.

Counter Dividers Part Context

This part belongs to the SN74LS697 family of synchronous counters. It integrates counting logic with output latching to maintain stable data states. The DW suffix indicates a plastic small-outline package variant suitable for surface mount assembly processes.
