DS3691VX

Overview

The DS3691VX is a low-power Schottky TTL TRI-STATE differential line driver manufactured by National Semiconductor. It features two buffered outputs with high source and sink current capability and internal short-circuit protection. The device operates with ±5V supplies, providing a ±10V output common-mode range in TRI-STATE mode and 0V output unbalance. It includes low current PNP inputs compatible with TTL, MOS, and CMOS logic families.

Feature Summary

• Internal short circuit protection for both source and sink outputs
• Capable of driving 100Ω transmission lines
• Low power consumption with typical I_CC of 9 mA per driver and I_EE of 5 mA per driver
• PNP inputs compatible with TTL, MOS, and CMOS logic levels

Applications

• Multipoint data bus systems
• Industrial control networks
• Telecommunications equipment

Procurement Notes

Verify the manufacturer datasheet to confirm electrical specifications and pinout compatibility before integration. Ensure the supply voltage matches the required ±5V operation. Check for any specific environmental or qualification requirements relevant to the target application environment.

Selection Notes

Select this component when a differential line driver with TRI-STATE capability is required for multipoint applications. Verify that the input logic levels are compatible with the system's TTL, MOS, or CMOS standards. Consider the power consumption characteristics relative to other drivers in the same family.

Part Context

The DS3691VX belongs to the DS1692/DS3692 family of TRI-STATE differential line drivers. These devices are electrically similar to the DS1691A/DS3691 but tested to meet MIL-STD-188-114A requirements. The 'VX' suffix typically indicates a specific package type, such as SOIC, within the manufacturer's lineup.

Replacement Considerations

The DS1691A and DS3691 are direct functional equivalents within the same product family. Cross-reference with DS1692/DS3692 variants if MIL-STD-188-114A compliance is required, noting that external components may be needed for full type 1 specification adherence.
