DC ELECTRICAL CHARACTERISTICS OVER OPERATING RANGE
FollowingConditionsApplyUnlessOtherwiseSpecified:
Industrial: TA = –40°C to +85°C, VCC = 5.0V ±5%; Military: TA = –55°C to +125°C, VCC = 5.0V ±10%
NOTES:
1. For conditions shown as Min. or Max., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 5.0V, +25°C ambient.
3. Not more than one output should be tested at one time. Duration of the test should not exceed one second.
4. The test limit for this parameter is ±5A at TA = –55°C.
5. This parameter is guaranteed but not tested.

OUTPUT DRIVE CHARACTERISTICS
NOTES:
1. H = HIGH
L = LOW
X = Don't Care
↑ = LOW-to-HIGH transition.
Select control = L: clocks can occur simultaneously.
Select control = H: clocks must be staggered in order to load both registers.
2. The data output functions may be enabled or disabled by various signals at the GAB or GBA inputs. Data input functions are always enabled, i.e. data at the bus pins will be
stored on every LOW-to-HIGH transition on the clock inputs.
3. A in B Register.
4. B in A Register.
