Am100470

Am100470 is a fully decoded 4096-bit ECL RAM organized 4096 words by one bit.There are some features of Am100470as follows.First is fast access time (12 ns typ.) which improves system cycle speeds.The second is enhanced output voltage level compensation providing 6X (improvement in ) VOL and VOH stability over supply and temperature ranges.Then is internally voltage and temperature compensated providing flat AC performances.Next is outputs preconditioned during write cycle eliminating write recovery glitch.The fifth is emitter follower outputs--easy write-ORing.At last, power dissipation decreases with increasing temperature.

What comes next is about the absolute maximum ratings of Am100470.The ambient temperature with power applied is from -55 to +125.The storage temperature is from -65 to 150.The VEE (pin potential to GND pin) is from -7.0 to +0.5 V.The input voltage (DC) is from VEE to +0.5 V.The output current (DC output high) is from -30 to +0.1 mA.Then is about the operating ranges.The ambient temperature is from 0 to +85.The supply voltage is from -5.7 to -4.2 V.

The following is about the DC characteristics of Am100470(VEE=-4.5 V,VCC=GND).The minimum VOH (output high voltage) is -1025 V, the typical is -955 V and the maximum is -880 mV, the minimum VOL (output low voltage) is -1810 V, the typical is -1715 V and the maximum is -1620 mV at VIN=VINHA or VILB.The minimum VIH (input HIGH voltage) is -1165 V and the maximum is -880 V when guaranteed input voltage high for all inputs.The minimum VIL (input LOW voltage) is -1810 mV and the maximum is -1475 mV when guaranteed input voltage low for all inputs.
