Overview
The SN74H53N is a TTL/H/L series logic integrated circuit manufactured by Texas Instruments. It functions as an AND-OR-Invert (AOI) gate with one functional unit and nine inputs. The device utilizes a 14-pin Plastic Dual In-Line Package (PDIP). Electrical specifications include a maximum propagation delay of 20 ns at a load capacitance of 25 pF. The operating supply voltage range spans from 4.75 V to 5.25 V, with a nominal supply voltage of 5 V. The component supports a maximum supply current of 25 mA and operates within a temperature range of -55 °C to +70 °C.
Feature Summary
- Implements complex logic functions through an AND-OR-Invert structure.
Applications
- Digital logic circuits requiring specific Boolean combinations.
Procurement Notes
Verify the exact datasheet revision and manufacturer source when sourcing this component. Confirm that the PDIP-14 package matches your PCB footprint requirements. Ensure the supply voltage constraints align with your system design. Check for any specific handling instructions related to legacy TTL components.
Selection Notes
Select this component when a dedicated AND-OR-Invert function is required in a digital design. It serves as a direct replacement for other TTL AOI gates in compatible systems. Consider the 14-pin DIP package for through-hole prototyping or legacy board maintenance. Verify input compatibility with standard TTL logic levels.
Part Context
This part belongs to the Texas Instruments SN74 series of logic ICs. It is categorized under Gates and Inverters. The SN74H53N provides a specialized logic function distinct from standard NAND or NOR gates. It is part of the broader family of discrete logic components used in digital electronics.
Replacement Considerations
Compatible substitutes may include other TTL AOI gates such as the SN74S53 or SN74LS53, provided pinouts and electrical characteristics are verified against the original design requirements.
