1. General description
The 74AVC1T8832 is a single dual-supply translating 2-input OR with strobe inputs. It features
two data input pins (A, B), two strobe input pins (STRA, STRB), one data output pin (Y) 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, B, STRA and STRB are referenced to
VCC(A) and pin Y is referenced to VCC(B).
The logic equation provided at the Y output is:
Y = STRA•A + STRB•B
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, the Y output is in
the high-impedance OFF-state.
