Frequently Asked Questions
What supply voltage and output sink current does the CD54ACT32F3A support for driving bus loads?
The CD54ACT32F3A operates from a 5V supply and provides an output sink current (I_OL) of 24 mA per output. This 24 mA drive strength allows each of the 4 OR gate outputs to directly sink current through resistive loads or drive TTL-compatible gate inputs without external buffer stages, even at a 50 pF load capacitance.
Why is the ceramic DIP package of CD54ACT32F3A preferred over plastic DIP packages in avionics applications?
The ceramic 14-pin DIP (JESD-30 code R-GDIP-T14) provides hermetic sealing that excludes moisture and corrosive gases, critical in avionics where the operating temperature spans -55°C to +125°C. Ceramic packages dissipate heat more efficiently than plastic at high ambient temperatures, maintaining the ACT logic switching characteristics at the rated 50 pF load capacitance throughout the mission profile.
How does the ACT family logic of CD54ACT32F3A interface with both TTL and CMOS logic families in mixed-logic PCB designs?
ACT inputs accept TTL logic levels with V_IH of 2.0V minimum and V_IL of 0.8V maximum, while producing CMOS output levels near the 5V rail. This allows the CD54ACT32F3A to receive signals from TTL devices at lower output swing margins and drive high-impedance CMOS inputs across all 4 two-input OR gates, enabling mixed-family signal aggregation without level-shifting circuits.
In a combinational logic design aggregating 4 interrupt signals, how many CD54ACT32F3A devices are needed and what propagation delay is expected?
A single CD54ACT32F3A provides all 4 two-input OR gates needed to aggregate 4 pairs of interrupt signals, or to build a 4-input OR function using 3 of the 4 gates in a tree. The ACT family propagation delay at 50 pF load and 5V supply is typically 5 ns to 7 ns, supporting logic tree depths up to 10 stages within a 70 ns system response budget.
