SN74CBTLV16800
LOW-VOLTAGE 20-BIT FET BUS SWITCH Memberof the Instruments Widebus™
Family 5-Ω Switch Connection Between Two Ports Rail-to-Rail Switching on Data I/O Ports ESD Protection Exceeds JESD22 2000-V Human-Body Model (A114-A) 200-V Machine Model (A115-A)The SN74CBTLV16800 provides 20 bits of
high-speed bus switching. The low on-state
resistance of the allows connections to be
made with minimal propagation delay. The device
also prechargesB porttoa user-selectable bias
voltage (BIASV) live-insertion noise.
The deviceis organized as dual 10-bit bus switches
with separate output-enable (OE) inputs.It can be
used as two 10-bit bus switchesor one 20-bit bus
switch. When OE low, the associated 10-bit bus
switchis on, andAis connectedto portB. Whenis high, theis open, the high-impedance
state exists between the two ports, and portBis
precharged to BIASV through the equivalent ofa
10-kΩ resistor.
This deviceis fully for partial-power-down applications usingIoff. TheIoff feature ensures that damaging
current will not backflow through the device whenitis powered The device has isolation during power off. ensure the high-impedance state during power upor power down, OE should be tiedtoVCC througha pullup
resistor; the minimum valueof the resistoris determinedby current-sinking capabilityof the driver.
