A functional equivalent in the same 74HCT family is the CD74HCT132M96, but that is a NAND gate with Schmitt-trigger inputs, not a direct OR-gate replacement. For a pin-compatible OR gate, stick with the 74HCT32 or 74HC32 in the same DIP footprint."},{"question":"Can CD74HCT32E replace 74HC32?","answer":"Yes, the CD74HCT32E can replace a 74HC32 in a 5V system. The HCT variant has TTL-compatible input thresholds (0.8V low, 2V high), while the HC variant uses CMOS thresholds (roughly 1.5V at 5V). If your driving logic is TTL-level, the HCT version is the correct choice. If the driver is CMOS, either works, but the HCT version draws slightly more input current."},{"question":"Can CD74HCT32E be used with 5V supply?","answer":"Yes, the CD74HCT32E is designed for a 4.5V to 5.5V supply range, making it fully compatible with 5V TTL and CMOS systems. The 5V rail is its nominal operating voltage."},{"question":"What is the difference between CD74HCT32E and CD74HC32E?","answer":"The CD74HCT32E has TTL-compatible input thresholds (0.8V low, 2V high), while the CD74HC32E uses CMOS thresholds (typically 1.5V at 5V). Both are quad 2-input OR gates in the same pinout and package. The HCT version is the right pick when interfacing to TTL logic outputs; the HC version is preferred for pure CMOS systems where lower input current matters."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD74HCT32E","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD74HCT32E when reusing this data.
