74AVCH1T45GS: Dual-supply voltage level translator/transceiver; 3-state
The 74AVCH1T45 is a single bit, dual supply transceiver that enables bidirectional level
translation. It features two 1-bit input-output ports (A and B), a direction control input (DIR)
and dual supply pins (VCC(A) and VCC(B)). Both VCC(A) and VCC(B) can be supplied at any
voltage between 0.8 V and 3.6 V making the device suitable for translating between any of
the low voltage nodes (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V). Pins A and DIR are
referenced to VCC(A) and pin B is referenced to VCC(B). 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.
The 74AVCH1T45 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.
