IDT74CBTLV3383 LOW-VOLTAGE 10-BIT BUS-EXCHANGE SWITCH INDUSTRIAL TEMPERATURE RANGE LOW-VOLTAGE 10-BIT BUS-EXCHANGE SWITCH FEATURES: IDT74CBTLV3383 DESCRIPTION: 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 SSOP, QSOP and TSSOP packages • • • • • • The CBTLV3383 provides ten bits of high-speed bus switching or exchanging with low on-switch resistance of the switch allowing connections to be made with minimal propagation delay. The device operates as a 10-bit bus switch or a 5-bit bus exchanger, which provides swapping of the A and B pairs of signals. The bus-exchange function is selected when BX is high and BE is low. APPLICATIONS: • 3.3V High Speed Bus Switching and Bus Isolation • Crossbar Switching FUNCTIONAL BLOCK DIAGRAM 1A1 3 SIMPLIFIED SCHEMATIC, EACH SWITCH 2 SW 1B1 SW SW 1A2 5 4 SW 1B2 A 5A 1 21 20 SW B 5B 1 SW SW 5A2 BE BX 22 SW CONTROL CIRCUITRY 23 5B2 1 13 The IDT logo is a registered trademark of Integrated Device Technology, Inc.

Typical values are at VCC = 3.3V, +25°C ambient. 2. The increase in supply current is attributable to each current 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. On-state resistance is determined by the lower of the voltages of the two (A or B ) terminals.
