Am100474

Am100474 is a fully decoded 4096-bit ECL RAM organized 1024 words by 4 bits.There are some features of Am100474 as follows.First is fast access time (10 ns) 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 fully compatible with 100K series RCL logic--no board changes required.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 Am100474. The case 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 Am100474(VEE=-4.5 V,VCC=GND).The minimum VOH (output high voltage) is -1025 V and the maximum is -880 mV, the minimum VOL (output low voltage) is -1810 V and the maximum is -1620 mV at VIN=VINHA or VILB.The minimum VIH (input HIGH voltage) is -1810 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.
