74LVC(H)2T45-Q100: Dual supply translating transceiver; 3-state
The 74LVC2T45-Q100; 74LVCH2T45-Q100 are dual bit, dual supply translating
transceivers with 3-state outputs that enable bidirectional level translation. They feature
two 2-bits input-output ports (nA and nB), a direction control input (DIR) and dual supply
pins (VCC(A) and VCC(B)). Both VCC(A) and VCC(B) can be supplied with any voltage between
1.2 V and 5.5 V. This feature makes the device suitable for translating between any of the
low voltage nodes (1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V). Pins nA and DIR are
referenced to VCC(A) and pins nB are referenced to VCC(B). A HIGH on DIR allows
transmission from nA to nB and a LOW on DIR allows transmission from nB to nA.
The devices are 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 port and B port are in the high-impedance OFF-state.
Active bus hold circuitry in the 74LVCH2T45-Q100 holds unused or floating data inputs at
a valid logic level.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
