TC74LCX32F/FN/FT/FK is a low-voltage quad 2-input OR gate from Toshiba. It features low-voltage operation (VCC = 1.65 to 3.6 V) and is compatible with 5-V supply environment for inputs.
The TC74LCX32F is a low‑voltage CMOS quad 2‑input OR gate designed for 3.3 V systems but tolerant to 5 V inputs. It offers high‑speed propagation (tpd = 5.5 ns max) and low power dissipation, with protection against static discharge on all pins.
The device is supplied in multiple package types (JEDEC SOP, JEITA SOP, TSSOP, VSSOP) and includes power‑down protection on inputs and outputs. Absolute maximum ratings, operating ranges, and detailed electrical characteristics are provided for reliable circuit design.
