Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant (SO-8) against the required footprint and thermal constraints. Confirm that the commercial temperature range (0°C to 70°C) meets the system's environmental requirements. Ensure input signals remain within the specified voltage limits to prevent damage to the diode-clamped inputs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when NOR logic functionality is required alongside high-current sinking capabilities. It serves as a direct replacement for older SN75450 family devices. Consider the SO-8 package dimensions if space is limited compared to through-hole options. Verify compatibility with the system's logic voltage levels.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN7545xB series of dual peripheral drivers manufactured by Texas Instruments. The 'B' suffix indicates updated specifications ensuring freedom from latch-up after conducting rated current. The PS suffix denotes the small-outline (SO) plastic package. This family replaces previous iterations like the SN75450A while maintaining functional interchangeability.

Buffers, Drivers, Receivers, Transceivers FAQ

What logic function does the SN75454B provide?

The SN75454B provides dual NOR logic functions. In positive logic, the output turns on (pulls to ground) when either or both inputs are low, and remains off only when both inputs are high.

How are the inputs protected?

The inputs are diode-clamped to simplify circuit design and ensure compatibility with TTL logic levels. Unused inputs should be connected to ground or VCC to prevent unknown states.
