Overview
The SNJ55462JG is a dual peripheral driver from the SN5546x series, designed for high-voltage and high-current applications. It features TTL-compatible diode-clamped inputs and operates with supply voltages between 4.5 V and 5.5 V. The device provides medium-speed switching capabilities and supports continuous output currents up to 300 mA. It is characterized for operation over the full military temperature range of -55 °C to 125 °C and utilizes an 8-pin ceramic dual in-line package (CDIP).
Feature Summary
- High-voltage outputs capable of withstanding breakdown voltages exceeding standard devices.
- Immunity to latch-up at 30 V even after conducting 300 mA.
- TTL-compatible diode-clamped inputs for direct logic interfacing.
- Military-grade reliability with extended temperature characterization.
Applications
- Relay drivers
- Lamp drivers
- MOS drivers
- Line drivers
Procurement Notes
Verify that the ordering suffix JG corresponds to the Ceramic Dual In-Line Package (CDIP) variant. Confirm the component meets QML certification requirements if intended for defense or aerospace procurement. Ensure the specific revision level matches system documentation. Validate pinout compatibility during integration planning.
Selection Notes
Select this component when higher breakdown voltage tolerance is required compared to standard peripheral drivers. Consider the trade-off between increased voltage capability and slightly slower switching speeds. Verify that the 300 mA continuous current rating aligns with load requirements. Ensure the CDIP package fits the available board space and mounting constraints.
Part Context
This part belongs to the SN5546x series, which includes AND, NAND, and OR driver variants. It serves as a high-voltage alternative to the SN55451B through SN55453B series. The SNJ prefix indicates a military-qualified version manufactured by Texas Instruments.
Replacement Considerations
Functionally interchangeable with SN55451B through SN55453B and SN75451B through SN75453B peripheral drivers.
