74CBTLV16245 LOW-VOLTAGE 16-BIT BUS SWITCH INDUSTRIAL TEMPERATURE RANGE 74CBTLV16245 LOW-VOLTAGE 16-BIT BUS SWITCH FEATURES: DESCRIPTION: 5 A/B bi-directional switch The CBTLV16245 is a set of 16-bit bus switches. It has standard 16245 Isolation Under Power-Off Conditions pinouts. The device is organized as dual 8-bit low resistance switches with Over-voltage tolerant independent Output Enable (xOE) control inputs. The switches can be Latch-up performance exceeds 100mA turned on under the control of the LVTTL-compatible Output Enable signals VCC = 2.3V - 3.6V, normal range (xOE) for bidirectional data flow between port A and port B. When xOE is ESD >2000V per MIL-STD-883, Method 3015 >200V using high, the switch is off and a high impedance exists between Port A and Port machine model (C = 200pF, R = 0) B. Available in TSSOP package To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor.
