Description

The 74AVCH1T45GW is a single-bit dual supply Voltage Level Translator/Transceiver that enables bidirectional level translation. It features two 1-bit input-output ports, a direction control input and dual supply pins. Both VCC(A) and VCC(B) can be supplied at any voltage between 0.8 and 3.6V making the device suitable for translating between any of the low voltage nodes. A HIGH on DIR allows transmission from A to B and a LOW on DIR allows transmission from B to A. The device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing any damaging backflow current through the device when it is powered down. In suspend mode when either VCC(A) or VCC(B) are at GND level, both A and B are in the high-impedance OFF-state. It has active bus hold circuitry which is provided to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors.
High noise immunity
IOFF circuitry provides partial power-down mode operation
Suspend mode
Bus hold on data inputs
Latch-up performance exceeds 100mA per JESD 78 class II
Inputs accept voltages up to 3.6V
Low noise overshoot and undershoot <10% of VCC
