DESCRIPTION/ORDERING INFORMATION  
The 'LVTH162245 devices are 16-bit (dual-octal) noninverting 3-state transceivers designed for low-voltage  
(3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.  
These devices can be used as two 8-bit transceivers or one 16-bit transceiver. The devices allow data  
transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic 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.  
The logic levels of the direction-control (DIR) input and the output-enable (OE) input activate either the B-port  
outputs or the A-port outputs or place both output ports into the high-impedance mode. The device transmits  
data from the A bus to the B bus when the B-port outputs are activated, and from the B bus to the A bus when  
the A-port outputs are activated. The input circuitry on both A and B ports is always active and must have a logic  
HIGH or LOW level applied to prevent excess ICC and ICCZ  
.
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown  
resistors with the bus-hold circuitry is not recommended.  
The A-port outputs, which are designed to source or sink up to 12 mA, include equivalent 22-Ω series resistors  
to reduce overshoot and undershoot.
