HD74LS32P OR GATE

The HD74LS32P is a common digital integrated circuit, specifically a Quad 2-Input OR Gate from the 74LS (Low-Power Schottky) logic family.

Here are its core specifications and relevance:

• Type: Logic Gate / Digital Integrated Circuit (IC).

• Function: Contains four independent 2-input OR gates. The output is high if at least one input is high.

• Family:LS (Low-Power Schottky), offering a balance of speed and power consumption for general control tasks.

• Supply Voltage (V_CC): Standard TTL voltage of 5.0V.

• Package: Standard 14-pin Dual In-line Package (DIP) (the 'P' suffix often denotes DIP).

• Relevance to Safety/Compliance: This chip would be used in the low-voltage control circuitry to implement protection and status logic, directly supporting the safety requirements in the Canvas:

  • Fault Aggregation: An OR gate is perfect for combining multiple potential fault signals into a single output. For instance, if you have an "Over-current Trip" OR a "Thermal Switch Trip" (120C protection), the OR gate output goes high, triggering the system shutdown.

  • Conditional Enable: Used to ensure the system is operational if one of several non-critical conditions is met.
