Notes
: 1. Absolute Maximum specifications mean the device will not be damaged if operated under these conditions. It does not guarantee performance. 2. Differential input/output voltage is measured at the noninverting terminal A with respect to the inverting terminal B. 3. Δ|V | and Δ|V | are the changes in magnitude of V and V , respectively, that occur when the input is changed from one logic state to OD OC OD OC the other. 4. Includes 10 ns read enable time. Maximum propagation delay is 25 ns after read assertion. 5. Pulse skew is defined as |t – t | of each channel. PLH PHL 6. Skew limit is the maximum propagation delay difference between any two devices at 25°C. 7. The relevant test and measurement methods are given in the “High Magnetic Immunity” section on p. 11. 8. External magnetic field immunity is improved by this factor if the field direction is “end-to-end” rather than to “pin-to-pin” (see diagram on p. 13). 8 NVE Corporation 11409 Valley View Road, Eden Prairie, MN 55344 (952) 829-9217 www.nve.com YouTube.com/NveCorporation iso-apps@ www.nve.com
