Frequently Asked Questions
How many independent logic functions does the LEOAC08PT provide, and what gate topology does it use?
The LEOAC08PT contains 4 independent 2-input AND gates in a single 20-pin TSSOP package, providing combinational logic for signal gating, enable control, and interlock functions. Each gate can independently drive loads with up to 24 mA output current, supporting a variety of fanout configurations.
What radiation hardening makes the LEOAC08PT suitable for satellite and space missions?
The LEOAC08PT is rad-hard rated, using a plastic TSSOP package on a radiation-tolerant process node that resists total ionizing dose effects and single-event latch-up. This allows it to maintain correct logic behavior in low-earth orbit and geosynchronous environments where commercial AC-family devices would accumulate functional errors over time.
How does the 50 pF specified load capacitance of the LEOAC08PT affect timing in high-speed aerospace signal chains?
The 50 pF load capacitance specification defines the test condition under which propagation delay and output transition times are characterized for the LEOAC08PT. Designers driving lower-capacitance PCB traces will see faster edges than the datasheet worst case, while traces exceeding 50 pF may require buffer insertion to maintain timing margins in clock distribution or control logic paths.
