74CBTLV3384 LOW-VOLTAGE 10-BIT BUS SWITCH INDUSTRIAL TEMPERATURE RANGE 74CBTLV3384 LOW-VOLTAGE 10-BIT BUS SWITCH DESCRIPTION: FEATURES: 5Ω Ω A/B bi-directional bus 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 QSOP and TSSOP packages The CBTLV3384 is a ten bit high-speed bus switch with low on-state resistance of the switch allowing connections to be made with minimal propagation delay. The device is organized as dual 5-bit bus switches with separate outputenable (OE) inputs, to allow use as two 5-bit bus switches or one 10-bit bus switch. When OE is low, the associated 5-bit bus switch is on and A port is connected to B port. When OE is high, the switch is open, and a highimpedance state exists between the two ports. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. • • • • • • APPLICATIONS: • 3.3V High Speed Bus Switching and Bus Isolation FUNCTIONAL BLOCK DIAGRAM 1A1 1A5 3 11 SW SW SIMPLIFIED SCHEMATIC, EACH SWITCH 2 10 1B1 1B5 1 2A1 14 B A 1OE SW 15 2B1 OE 2A5 2OE 22 SW 10 2B5 13 INDUSTRIAL TEMPERATURE RANGE MAY 2019 1 © 2019 Integrated Device Technology, Inc.

The increase in supply current is attributable to each current that is at the specified voltage level rather than VCC or GND. 2. This is measured by the voltage drop between the A and B terminals at the indicated current through the switch. On-state resistance is determined by the lower of the voltages of the two (A or B ) terminals.
