What are the key features of LEOAC32PT?
- 4 independent 2-input OR gate cells in a single TSSOP-20 package
- Radiation-hardened (rad-hard) plastic construction for space and harsh-environment use
- AC CMOS logic family with high-speed operation and low static power
- 24 mA output sink current per gate for driving bus lines and backplane loads
- 50 pF load capacitance rating for stable timing on PCB traces
- Plastic/epoxy package body balances cost and radiation tolerance
What is LEOAC32PT used for?
LEOAC32PT is designed for space-qualified and radiation-hardened logic circuits aboard satellites, launch vehicles, and high-altitude platforms where total ionizing dose and single-event upsets are design constraints. Its quad 2-input OR gate architecture supports redundancy voting logic, interrupt combiners, and enable-signal ORing in FPGA or ASIC glue-logic layers. The AC family speed and 24 mA drive strength also make it suitable for high-reliability industrial control systems demanding long-term logic integrity.

Frequently Asked Questions
Which digital logic functions can LEOAC32PT implement in a space-constrained design?
LEOAC32PT provides 4 independent OR-gate functions with 2 inputs each, making it useful for glue logic, enable combining, and control-signal aggregation.
How much output drive is available from this STMicroelectronics AC logic part?
The fetched specifications list 24 mA maximum low-level output current and 50 pF load capacitance, supporting moderate digital fanout in qualified logic circuits.
What package compatibility checks apply before replacing another quad OR gate?
LEOAC32PT is identified with a TSSOP-20 equivalent package code, so engineers should verify 20-pin footprint, pinout, and height against the existing PCB.
Why should buyers confirm qualification details for this logic IC?
Because LEOAC32PT is described as radiation-hardened plastic logic, procurement should verify lot traceability, compliance documents, and the $4.50 stock offer before purchase.
