DC Electrical Characteristics over Operating Range for eHSTL 1 Symbol Parameter Test Conditions Min Typ 7 Max Unit Input Characteristics IIH Input HIGH Current 9 VDD = 2.6V VI = VDDQ/GND ±5 IIL Input LOW Current 9 VDD = 2.6V VI = GND/VDDQ ±5 µA VIK Clamp Diode Voltage VDD = 2.4V, IIN = -18mA - 0.7 - 1.2 V VIN DC Input Voltage -0.3 +3.6 V VDIF DC Differential Voltage 2,8 0.2 V VCM DC Common Mode Input Voltage 3,8 800 900 1000 mV VIH DC Input HIGH 4,5,8 VREF+ 100 - mV VIL DC Input LOW 4,6,8 VREF-100 mV VREF Single-Ended Reference Voltage 4,8 900 mV Output Characteristics IOH= -8mA VDDQ- 0.4 V VOH Output HIGH Voltage IOH= -100µA VDDQ- 0.1 V IOL= 8mA 0.4 V VOL Output LOW Voltage IOL= 100µA 0.1 V NOTES: 1. See RECOMMENDED OPERATING RANGE table. 2. VDIF specifies the minimum input differential voltage (VTR - VCP) required for switching where VTR is the "true" input level and VCP is the "complement" input level. Differential mode only. The DC differential voltage must be maintained to guarantee retaining the existing HIGH or LOW input. The AC differential voltage must be achieved to guarantee switching to a new state. 3. VCM specifies the maximum allowable range of (VTR + VCP) /2. Differential mode only. 4. For single-ended operation, in a differential mode, A/VREF is tied to the DC voltage VREF. 5. Voltage required to maintain a logic HIGH, single-ended operation in differential mode. 6. Voltage required to maintain a logic LOW, single-ended operation in differential mode. 7. Typical values are at VDD = 2.5V, VDDQ = 1.8V, +25°C ambient. 8. The reference clock input is capable of HSTL, eHSTL, LVEPECL, 1.8V or 2.5V LVTTL operation independent of the device output. The correct input interface table should be referenced. 9. For differential mode (RxS = LOW), A and A/VREF must be at the opposite rail.

These power consumption characteristics are for all the valid input interfaces and cover the worst case input and output interface combinations. 2. The termination resistors are excluded from these measurements. 3. If the differential input interface is used, the true input is held LOW and the complementary input is held HIGH. |
