The ’AHCT16245 devices are 16-bit (dual-octal)  
noninverting 3-state transceivers designed for  
synchronous two-way communication between  
data buses. The control-function implementation  
minimizes external timing requirements.

These devices can be used as two 8-bit  
transceivers or one 16-bit transceiver. They allow  
data transmission from the A bus to the B bus or  
fromtheBbustotheAbus, dependingonthelogic  
level at the direction-control (DIR) input. The  
output-enable (OE) input can be used to disable  
the device so that the buses are effectively  
isolated.

through a pullup resistor; the minimum value of  
the resistor is determined by the current-sinking
