18-Bit Undershoot/Overshoot Clamp
and ESD Protection Device
General Description
The 74F1071 is an 18-bit undershoot/overshoot clamp
which is designed to limit bus voltages and also to protect
more sensitive devices from electrical overstress due to
electrostatic discharge (ESD). The inputs of the device
aggressively clamp voltage excursions nominally at 0.5V
below and 7V above ground.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
