74CBTLV16292 LOW-VOLTAGE 12-BIT 1:2 MUX / DEMUX BUS SWITCH INDUSTRIAL TEMPERATURE RANGE LOW-VOLTAGE 12-BIT 1:2 74CBTLV16292 MUX / DEMUX BUS SWITCH WITH INTERNAL PULL DOWN RESISTORS FEATURES: DESCRIPTION: The CBTLV16292 is a single 12-bit multiplexing / demultiplexing bus 5 A/B bi-directional switch switch, which provides high speed switching. This device has very low ON Isolation Under Power-Off Conditions resistance, resulting in under 250ps propagation delay throught the switch. Make-before-break feature The demultiplexer side has a 500 resistor (R pulldown) termination to Over-voltage tolerant GND to eliminate floating nodes. Internal 500 pull-down resistor to GND When the select (S) input is low, the A port is connected to the B1 port, Latch-up performance exceeds 100mA and the R pulldown is connected to the B2 port. Similarly, when the S input VCC = 2.3V - 3.6V, normal range is high, A port is connected to B2 port and the R pulldown is connected to ESD >2000V per MIL-STD-883, Method 3015 >200V using B1 port. machine model (C = 200pF, R = 0) Available in TSSOP package APPLICATIONS: 3.3V High Speed Bus Switching and Bus Isolation Resource sharing FUNCTIONAL BLOCK DIAGRAM SIMPLIFIED SCHEMATIC, EACH SWITCH 54 2 1A SW 1B1 RPULLDOWN RPULLDOWN AB 53 SW 1B2 27 30 SW 12A 12B1 RPULLDOWN SELECT CONTROL CIRCUITRY RPULLDOWN 30 SW 12B2 1 S The IDT logo is a registered trademark of Integrated Device Technology, Inc.
