Am8127

The Am8127 is a kind of clock generator and controller which provides clock oscillator,frequency dividers and clock drivers for the complete array of AmZ8000 CPUs,peripherals and memory system configurations.There are some features as follows.First is high-drive high-level clock output.The second is synchronized WAIT state and time-out controls.The last one is four TTL-level clocks.

What comes next is about the absolute maximum ratings of Am8127.The storage temperature is from -65 to +150.The temperature (ambient) under bias is from -55 to +125.The supply voltage to ground potential (Pin 24 to Pin 12) continuous is from -0.5 to +7.0 V.The DC voltage applied to outputs for high output state is from -0.5 to +V_CC max.The DC input voltage at X1,4/3,SSNO,SSNC,RUN/HALT is from -0.5 to V_CC+0.5 V and is from -0.5 to +5.5 V at other inputs.The DC voltage applied to C is from -0.5 to +8 V.The DC output current into outputs is 30 mA.The DC input current is from -30 to +5.0 mA.The temperature is from 0 to 70 and the supply voltage is from +4.75 to +5.25 V for commercial (C) devices.The temperature is from -55 to +125 and the supply voltage is from +4.5 to +5.5 V for military (M) devices.

The following is about the DC characteristics over operating range of Am8127 unless otherwise specified.The maximum V_OL (output low voltage) is 0.40 V at I_OL=0.1 mA,ZCK output and 0.5 V at I_OL=16 mA,TTL output.The minimum V_OH (output high voltage) is V_CC-0.4 V and the typical is V_CC-0.1 V at I_OH=-0.1 mA at ZCK output.The maximum V_I (input clamp voltage) is -1.5 V at V_CC=MIN,I_IN=-16 mA,The minimum V_IN-V_IL (RESETIN hysteresis) is 400 mV and the typical is 650 mV at V_CC=MIN.
