N74F269D,602

Counter Dividers Overview

The N74F269D,602 is an 8-bit bidirectional binary counter from the 74F series. It features synchronous counting and loading with a preset capability for programmable operation. The device includes built-in look-ahead carry for easy cascading and a U/D input to control counting direction. All state changes are initiated by the rising edge of the clock. It operates within a supply voltage range of 4.5V to 5.5V and supports a typical maximum clock frequency of 115MHz.

Counter Dividers Feature Summary

• Synchronous counting and parallel loading initiated by the rising edge of the clock signal
• Built-in look-ahead carry capability facilitates easy cascading of multiple stages
• Up/Down count control input allows bidirectional counting operations

Counter Dividers Applications

• Synchronous multistage counting schemes
• Programmable counters using preset capability
• Bidirectional binary counting applications

Counter Dividers Procurement Notes

Verify the specific package type required, as the D suffix indicates a Plastic Small Outline Package (SOL). Confirm that the commercial temperature range of 0°C to +70°C meets system requirements. Ensure the 5V ±10% supply voltage specification aligns with the target circuit design before procurement.

Counter Dividers Selection Notes

Select this component when an 8-bit fully synchronous counter with bidirectional capabilities is needed. The look-ahead carry feature makes it suitable for high-speed cascading applications compared to ripple counters. Verify that the 74F logic family speed and power consumption characteristics fit the overall system constraints.

Counter Dividers Part Context

This part belongs to the 74F (FAST) logic family, known for high-speed performance. The N74F269D variant specifically utilizes a 24-lead Plastic Small Outline Package (SOT137-1). It serves as a digital logic integrated circuit designed for general-purpose counting and timing applications in electronic systems.

Counter Dividers Replacement Considerations

The N74F269N,602 is a confirmed substitute part number offering identical functionality but housed in a 24-Pin Plastic Slim DIP package instead of the SOL package.
