Description

Out Of Range output. A differential high at these pins indicates that

79

OR+

the differential input is out of range (outside the range ±325 mV or

80

OR-

±435 mV as defined by the FSR pin).

Differential Clock outputs used to latch the output data. Delayed

and non-delayed data outputs are supplied synchronous to this

82

DCLK+

signal. This signal is at 1/2 the input clock rate in SDR mode and at

81

DCLK-

1/4 the input clock rate in the DDR mode. DCLK outputs are not

active during a calibration cycle.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

(1)

All voltages are measured with respect to GND = DR GND = 0V, unless otherwise specified.

(2)

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. There is no ensured specification of

operation at the Absolute Maximum Ratings. Operating Ratings indicate conditions for which the device is functional, but do not ensure

specific performance limits. For ensured specifications and test conditions, see the Electrical Characteristics. The ensured specifications

apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed

test conditions.

(3)

should be limited to 25 mA. The 50 mA maximum package input current rating limits the number of pins that can safely exceed the

power supplies with an input current of 25 mA to two. This limit is not placed upon the power, ground and digital output pins.

(4)

Human body model is 100 pF capacitor discharged through a 1.5 k

Ω resistor.
