FUNCTIONAL BLOCK DIAGRAM
LOW-VOLTAGE 16-BIT
BUS SWITCH
DESCRIPTION:
The CBTLV16245 is a set of 16-bit bus switches. It has standard 16245
pinouts. The device is organized as dual 8-bit low resistance switches with
independent Output Enable (xOE) control inputs. The switches can be
turned on under the control of the LVTTL-compatible Output Enable signals
(xOE) for bidirectional data flow between port A and port B. When xOE is
high, the switch is off and a high impedance exists between Port A and Port
B.
To ensure the high-impedance state during power up or power down,
OE should be tied to VCC through a pullup resistor.

DC ELECTRICAL CHARACTERISTICS OVER OPERATING RANGE
Following Conditions Apply Unless Otherwise Specified:
Operating Condition: TA = –40°C to +85°C
NOTES:
1. Typical values are at 3.3V, +25°C ambient.
2. The increase in supply current is attributable to each input that is at the specified voltage level rather than VCC or GND.
3. This is measured by the voltage drop between the A and B terminals at the indicated current through the switch.
