The SN74LVTH162245DL is a 16-bit (dual-octal) non-inverting 3-state Bus Transceiver designed for low-voltage (3.3V) VCC operation, but with the capability to provide a TTL interface to a 5V system environment. It can be used as two 8-bit transceivers or one 16-bit transceiver. The device allows 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 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.
● Support mixed-mode signal operation
● IOFF and power-up 3-state support hot insertion
● Bus hold on data inputs eliminates the need for external pull-up/pull-down resistors
● Distributed VCC and GND pins minimize high-speed switching noise
● Flow-through architecture optimizes PCB layout
● Latch-up performance exceeds 500mA per JESD 17
● Support unregulated battery operation down to 2.7V
● <0.8V at VCC = 3.3V, TA = 25°C VOLP (output ground bounce)
● Green product and no Sb/Br
