PIN GRID ARRAY THERMAL CHARACTERISTICS
Symbol
Parameter
θ JA
Junction to ambient thermal resistance
Notes : 1. Measured at 400 linear ft/min transverse air flow.
2. This parameter is sampled and not 100% tested.

Notes : 1. Except CLK.
2. Output continously driven.
3. Timings are tested using VOL=0.8V and with a suitable allowance for the time taken for the output to fall from 0.8V to 0.4V.
4. Output turn-off tests.

Notes : 1. Clock input transitions should be monotonic between the input thresholds of 0.5 V and 4.0 V.
2. For Rev.A parts tCHCL, tCLCH and tCHCH have maximum values of 50 000ns, 50 000ns and 100 000ns respectively.
(A minimum clock frequency of 10kHz.)
