74CBTLV16245 LOW-VOLTAGE 16-BIT BUS SWITCH INDUSTRIAL TEMPERATURE RANGE 74CBTLV16245 LOW-VOLTAGE 16-BIT BUS SWITCH FEATURES: DESCRIPTION: 5Ω Ω A/B bi-directional switch Isolation Under Power-Off Conditions Over-voltage tolerant Latch-up performance exceeds 100mA VCC = 2.3V - 3.6V, normal range ESD >2000V per MIL-STD-883, Method 3015; >200V using machine model (C = 200pF, R = 0) • Available in TSSOP package • • • • • • 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.

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.
