The 'HC4075 and 'HCT4075 logic gates utilize silicon-gate CMOS technology to achieve operating speeds similar to LSTTL gates with the low power consumption of standard CMOS integrated circuits. All devices have the ability to drive 10 LSTTL loads. The HCT logic family is functionally pin compatible with the standard LS logic family.
The CD74HC4075 and CD74HCT4075 are high‑speed CMOS logic triple 3‑input OR gates offered by Texas Instruments. They provide buffered inputs, low propagation delay and wide operating temperature range, and are pin‑compatible with standard LS logic families.
The document includes features, functional diagrams, absolute maximum ratings, electrical specifications, switching characteristics, ordering information, and packaging details for multiple package types such as PDIP, SOIC, SOP and TSSOP.
