Frequently Asked Questions
What are the key electrical parameters of the CD74HCT32M?
The CD74HCT32M features 4 two-input OR gates with a 50 pF load capacitance (CL), a maximum output sink current (IOL) of 4 mA, and is part of the HCT CMOS logic family. It operates with TTL-compatible input voltage thresholds and CMOS-level output, housed in a 14-pin Small Outline (SOIC) package.
What are the typical applications for the CD74HCT32M OR gate IC?
The CD74HCT32M is commonly used for digital signal routing, interrupt logic, data multiplexing, and combinational logic functions in industrial control systems, embedded processors, telecommunications equipment, and consumer electronics where TTL-to-CMOS interfacing is required.
What package type does the CD74HCT32M come in, and is it RoHS compliant?
The CD74HCT32M is housed in a 14-pin Small Outline Integrated Circuit (SOIC) package, conforming to JESD-30 code R-PDSO-G14. It carries JEDEC JESD-609 code e4, indicating a halogen-free, RoHS-compliant plastic/epoxy body suitable for lead-free assembly processes.
What is the difference between HCT and HC logic families for the CD74HCT32M?
The HCT family (like CD74HCT32M) accepts TTL-compatible input voltage levels (VIH min 2.0 V) while the HC family requires CMOS-level inputs (VIH min 3.5 V at 5 V supply). Both offer CMOS-level outputs and low power consumption, but HCT is specifically designed for direct interfacing with TTL and 5 V microcontroller outputs without level-shifting circuits.
