SNJ55461FK

Overview

The SNJ55461FK is a dual peripheral driver from the SN55461 series, housed in a 20-pin LCCC package. It operates over a military temperature range of -55°C to 125°C with a nominal supply voltage of 5V (4.5V to 5.5V). The device provides high-voltage outputs capable of withstanding up to 30V without latch-up after conducting 300mA. It features TTL-compatible diode-clamped inputs and supports continuous output currents up to 400mA.

Feature Summary

High-voltage output capability designed for breakdown voltages exceeding standard peripheral drivers
Immunity to output latch-up at 30V even after conducting rated current
TTL-compatible diode-clamped inputs for direct logic interfacing
Military-grade characterization ensuring reliable operation across extreme temperatures

Applications

Logic buffers requiring high-voltage tolerance
Power drivers for loads exceeding standard logic levels
Relay drivers in industrial control systems
Lamp drivers for lighting applications
MOS drivers for field-effect transistor switching

Procurement Notes

Verify that the specific ordering suffix FK corresponds to the Leadless Ceramic Chip Carrier package configuration. Confirm that the SN prefix indicates QML certification requirements if the application demands military or defense qualification standards. Ensure the procurement documentation explicitly references the SNJ55461FK part number to distinguish it from commercial variants.

Selection Notes

Select this component when system designs require higher breakdown voltages than standard peripheral drivers can provide. It is suitable for applications needing medium-speed switching with robust high-current handling capabilities. Consider the LCCC package constraints regarding thermal dissipation and board space compared to plastic DIP alternatives.

Part Context

This device belongs to the SN55461/75461 series of dual peripheral drivers. It is functionally interchangeable with older SN55451B through SN55453B and SN75451B through SN75453B devices but offers improved high-voltage performance. The SN55461 variant specifically targets military environments requiring full temperature range coverage.
