The document introduces the 74LCX07 low voltage hex buffer produced by Fairchild Semiconductor Corporation. The product features 5V tolerant inputs, 2.3V-5.5V operating voltage, high-speed operation, and low power consumption.
The 74LCX07 contains six buffers whose inputs tolerate voltages up to 7 V, allowing 5 V systems to interface with 3 V systems. Its open‑drain outputs can be wired together for active‑HIGH wire‑AND or active‑LOW wire‑OR functions, and the device includes patented noise/EMI reduction circuitry, latch‑up protection, and high ESD ratings.
The datasheet provides absolute maximum ratings, recommended operating conditions, DC and AC electrical characteristics, and detailed package information for SOIC (M14A), SOP (M14D) and TSSOP (MTC14) variants. Physical dimensions, land‑pattern recommendations, and ordering codes are also listed.
| Input voltage tolerance | Up to 7 V |
|---|---|
| 5 V‑tolerant inputs | Yes |
| Output drive current | +24 mA (Voc = 3.0 V) |
| Supply voltage (operating) | 2.0 V to 5.5 V |
| Input voltage (operating) | 0 V to 5.5 V |
| ESD rating (human body model) | > 2000 V |
The device can source up to +24 mA with a typical output voltage of 3.0 V.
The device must not be operated outside –0.5 V to +7.0 V on the supply pins.
