16-BIT BUS SWITCH

COMMERCIAL TEMPERATURE RANGE

DC ELECTRICAL CHARACTERISTICS OVER OPERATING RANGE

Following Conditions Apply Unless Otherwise Specified:

Commercial: TA = –40

°C to +85°C, VCC = 5.0V ±10%

NOTES:

1. For conditions shown as Max. or Min., 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. Measured by voltage drop between ports at indicated current through the switch.

1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.

2. Typical values are at VCC = 5.0V, +25

°C ambient.

3. Per TTL driven input (VIN = 3.4V). All other inputs at VCC or GND.

4. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations.

5. Values for these conditions are examples of the ICC formula. These limits are guaranteed but not tested.

6. IC = IQUIESCENT + IINPUTS + IDYNAMIC

IC = ICC +

∆ICC DHNT + ICCD (fiN)

ICC = Quiescent Current

∆ICC = Power Supply Current for a TTL High Input (VIN = 3.4V)

DH = Duty Cycle for TTL Inputs High

NT = Number of TTL Inputs at DH

ICCD = Dynamic Current Caused by an Input Transition Pair (HLH or LHL)

fi = Input Frequency

N = Number of Switches Toggling at fi

All currents are in milliamps and all frequencies are in megahertz.
