Frequently Asked Questions
What is the SN7432N and what logic function does it perform?
The SN7432N is a Quad 2-Input OR Gate IC from Texas Instruments. It contains four independent 2-input OR gates in a single DIP-14 package. Each gate outputs a HIGH signal when at least one of its two inputs is HIGH, making it essential for binary logic operations in digital circuits.
What are the key electrical specifications of the SN7432N?
The SN7432N operates on a 5.25V supply voltage and supports a maximum output sink current (I_ol) of 16mA. It has a load capacitance of 15pF and belongs to the standard TTL/H/L logic family. The package is a 14-pin DIP (PDIP), suitable for through-hole PCB assembly.
What are common applications for the SN7432N?
The SN7432N is used in address decoding, arithmetic logic units, interrupt combining circuits, and general digital logic designs. It is a staple in industrial control systems, educational electronics, retro computing boards, and any application requiring TTL-level OR logic operations.
Is the SN7432N RoHS compliant and still in production?
Yes, the SN7432N carries a Pbfree (RoHS compliant) code and has a YTEOL of 15 years, indicating long-term availability and lifecycle support. It remains a popular choice for both new designs and maintenance of existing TTL-based systems.
What package does the SN7432N come in and are there alternatives?
The SN7432N comes in a 14-pin Dual-In-Line Package (DIP-14), ideal for breadboarding and through-hole assembly. Alternative packages from Texas Instruments include the SN7432D (SOIC-14) and SN74LS32N for lower-power LSTTL applications. Pin-compatible alternatives exist from manufacturers such as ON Semiconductor and Nexperia.
