IDT74CBTLV16800  
LOW-VOLTAGE 20-BIT  
BUS SWITCH WITH  
PRECHARGED OUTPUTS  
FEATURES:  
DESCRIPTION:  
• 5Ω A/B bi-directional switch  
TheCBTLV16800provides20-bitsofhigh-speedbusswitchingwithlow  
on-state resistance of the switch allowing connections to be made with  
minimal propagation delay. The device also precharges the B port to a  
user-selectable bias voltage (BIASV)tominimize live-insertionnoise.  
The CBTLV16800 is organized as dual 10-bit bus switches with two  
different output-enable (OE) control inputs. When OE is low, the corre-  
sponding10-bitbus switchis onandportAis connectedtoportB.When  
OEis high,theswitchis open,andahighimpedancestateexists between  
the twoports, andportBis prechargedtoBIASVthroughthe equivalent  
ofa 10-kΩ resistor.  
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 and TVSOP packages  
Toensure the high-impedance state duringpoweruporpowerdown,  
OE shouldbe tiedtoVCCthrougha pullupresistor;the minimumvalue of  
the resistoris determinedbythe current-sinkingcapabilityofthe driver.  
APPLICATIONS:  
• 3.3V High Speed Bus Switching and Bus Isolation
