Overview
The Nexperia 74ABT32PW,112 is a quad 2-input OR gate in a TSSOP14 package. It operates on a supply voltage of 4.5 V to 5.5 V with TTL-compatible levels. Propagation delays range from 1.0 ns to 3.8 ns at 5.0 V. The device supports partial power-down via IOFF circuitry and withstands ESD up to 2000 V (HBM). Operating temperature spans -40 °C to +85 °C.
Feature Summary
- BiCMOS technology for high-speed operation and strong output drive capability
- IOFF circuitry enables partial power-down mode by disabling outputs to prevent backflow current
- Direct interface compatibility with TTL logic levels
- Latch-up protection exceeding 500 mA per JESD78B Class II Level A
Applications
- Partial power-down applications requiring controlled output disablement
- High-speed digital logic processing using OR gate functions
- Mixed-signal systems interfacing with TTL-level components
Procurement Notes
Verify the specific ordering suffix '112' against the manufacturer's official documentation to confirm the exact tape-and-reel packaging configuration. Confirm that the TSSOP14 variant matches the required board layout dimensions. Ensure the component status aligns with current production schedules before finalizing design-in decisions.
Selection Notes
Select this component when BiCMOS speed and direct TTL interfacing are required within a 5 V system. The TSSOP14 package suits space-constrained surface-mount designs. Verify that the 4.5 V to 5.5 V supply range fits the target application environment and that the propagation delay specifications meet the timing constraints.
Part Context
This part belongs to the 74ABT series of advanced BiCMOS logic devices. The 74ABT32 specifically provides four independent OR gates. The PW suffix indicates the TSSOP14 plastic thin shrink small outline package. This family is designed for high-performance digital applications requiring fast switching speeds.
Replacement Considerations
The 74ABT32PW,118 is a verified substitute offering identical electrical characteristics and functionality. Both parts utilize the same TSSOP14 package and pinout configuration, allowing for direct replacement without PCB redesign.
FAQ
How does the IOFF circuitry function during power-down?
The IOFF circuitry disables the outputs when the device is powered down, preventing potentially damaging backflow current through the device.
What is the maximum ESD protection rating for this component?
The device offers HBM protection exceeding 2000 V according to ANSI/ESDA/JEDEC JS-001 class 2 and CDM protection exceeding 1000 V according to JS-002 class C3.
