SNJ55462FK

Overview

The SNJ55462FK is a dual peripheral driver from the SN55462 series, designed for high-voltage and high-current applications. It operates over a military temperature range of -55°C to 125°C with a supply voltage (VCC) of 4.5 V to 5.5 V. The device features TTL-compatible diode-clamped inputs and provides NAND logic functionality. It supports continuous output currents up to 300 mA and peak currents up to 500 mA. The component utilizes an LCCC-20 package.

Feature Summary

• High-voltage outputs capable of withstanding breakdown voltages exceeding standard devices
• Immunity to output latch-up at 30 V after conducting rated current
• TTL-compatible diode-clamped inputs for direct interfacing
• Dual configuration providing independent NAND logic functions

Applications

• Logic buffers
• Power drivers
• Relay drivers
• Lamp drivers
• MOS drivers

Procurement Notes

Verify that the specific part number matches the required military grade specifications and temperature range. Confirm the LCCC-20 package type aligns with board layout requirements. Ensure compatibility with existing system voltage levels and current demands before procurement.

Selection Notes

Select this component when higher breakdown voltages are necessary compared to standard peripheral drivers. Consider the trade-off between increased voltage capability and slightly slower switching speeds. Verify that the dual NAND configuration meets the logical requirements of the circuit design.

Part Context

This device belongs to the SN55461/75461 series of peripheral drivers. It is functionally interchangeable with SN55451B through SN55453B and SN75451B through SN75453B, but offers enhanced breakdown voltage performance. The SNJ prefix indicates a military-grade qualification.
