SNJ55453BJG

Overview

The SNJ55453BJG is a dual peripheral driver from the SN5545xB family, featuring an OR logic gate configuration. It operates within a military temperature range of -55°C to 125°C and utilizes a ceramic dual in-line package (CDIP) with 8 pins. The device supports standard supply voltages between 4.5V and 5.5V, delivering high-current outputs up to 300mA with open-collector architecture. It provides high-voltage output capability up to 30V and includes diode-clamped inputs for TTL compatibility.

Feature Summary

• Dual-output drivers with integrated OR logic gates
• High-current driving capability up to 300mA
• Open-collector outputs supporting high-voltage loads
• Diode-clamped inputs ensuring TTL compatibility

Applications

• High-speed logic buffers
• Power drivers
• Lamp drivers
• LED drivers
• Line drivers

Procurement Notes

Verify the specific ordering suffix 'JG' corresponds to the CDIP package variant required for your design. Confirm that the military temperature rating (-55°C to 125°C) aligns with your environmental specifications. Ensure input channels are tied to defined logic levels rather than left floating to prevent undefined states during operation.

Selection Notes

Select this component when a dual-channel driver with OR logic functionality is required for high-current applications. It serves as a functional replacement for older SN75450 series devices while offering improved latch-up immunity. Consider the CDIP package constraints if transitioning from surface-mount designs or requiring hermetic sealing for harsh environments.

Part Context

This part belongs to the SNx545xB family of dual peripheral drivers manufactured by Texas Instruments. The family includes variants with AND, NAND, NOR, and OR logic functions. The SN5545xB designation specifically indicates components rated for the full military temperature range, distinguishing them from the commercial SN7545xB counterparts.
