Counter Dividers datasheet and documents for SN74LS69D
Counter Dividers Overview
The SN74LS69D is a Low-power Schottky (LS) series synchronous decade counter manufactured by Texas Instruments. It features a bidirectional counting mechanism and operates within a supply voltage range of 4.75 V to 5.25 V. The device is housed in a 14-pin SOIC surface-mount package with an operating temperature range of 0°C to +70°C. Key electrical characteristics include a maximum low-level output current of 8 mA, a maximum high-level output current of -0.4 mA, and a typical propagation delay of 39 ns at 5 V with a 15 pF load.
Counter Dividers Feature Summary
- Synchronous bidirectional decade counting capability
- Open-collector outputs for flexible interfacing
- Low-power Schottky logic technology
Counter Dividers Applications
- Digital frequency division circuits
- Binary-coded decimal (BCD) counters
- Timing sequence control systems
Counter Dividers Procurement Notes
Verify the specific suffix 'D' confirms the SOIC-14 package variant. Confirm RoHS compliance status as LS series availability varies. Ensure the supplier provides official datasheets matching the SN74LS69 specification. Check for obsolescence notices or lifecycle changes before finalizing procurement plans.
Counter Dividers Selection Notes
Select this component when a synchronous decade counter with bidirectional counting is required in a space-constrained design. The SOIC package suits automated surface-mount assembly. Verify that open-collector outputs align with the system's pull-up requirements and voltage levels.
Counter Dividers Part Context
This part belongs to the Texas Instruments 74LS family, known for balanced speed and power consumption. It serves as a fundamental building block for digital timing and sequencing applications requiring decade-based counting operations.
Counter Dividers Replacement Considerations
Compatible substitutes include the SN74LS90 for unidirectional counting or the SN74LS92/93 for different decade configurations. For pin-compatible alternatives, verify the SN74LS69A if enhanced noise immunity is needed.
