Product data sheet Rev. 02 — 3 August 2009 10 of 33 NXP Semiconductors 74AUP1T45 Low-power dual supply translating transceiver; 3-state [1] VCCI is the supply voltage associated with the data input port. [2] VCCO is the supply voltage associated with the output port. [3] For VCCI values not specified in the data sheet: minimum VIH = 0.7 × VCCI and maximum VIL = 0.3 × VCCI. [4] For VCCI values not specified in the data sheet: minimum VIH = 0.7 × VCC(A) and maximum VIL = 0.3 × VCC(A). [5] All unused data inputs of the device must be held at VCCI or GND to ensure proper device operation. ∆I OFF additional power-off leakage current A port; VI or VO = 0 V to 3.6 V; VCC(A) = 0 V to 0.2 V; VCC(B) = 1.1 V to 3.6 V -- ±0.75 µA B port; VI or VO = 0 V to 3.6 V; VCC(B) = 0 V to 0.2 V; VCC(A) = 1.1 V to 3.6 V -- ±0.75 µA DIR input; VI or VO = 0 V to 3.6 V; VCC(A) = 0 V to 0.2 V; VCC(B) = 1.1 V to 3.6 V -- ±0.75 µA ICC supply current A port; VI = GND or VCCI; IO = 0 A [1] VCC(A) = VCC(B) = 1.1 V to 3.6 V - - 1.4 µA VCC(A) = 3.6 V; VCC(B) = 0 V - - 1.4 µA VCC(A) = 0 V; VCC(B) = 3.6 V - 0 - µA B port; VI = GND or VCCI; IO = 0 A [1] VCC(A) = VCC(B) = 1.1 V to 3.6 V - - 1.4 µA VCC(A) = 3.6 V; VCC(B) = 0 V - 0 - µA VCC(A) = 0 V; VCC(B) = 3.6 V - - 1.4 µA A plus B port (ICC(A) + ICC(B)); IO = 0 A; VI = GND or VCCI; VCC(A) =VCC(B) = 1.1 V to 3.6 V [1] - - 1.4 µA ∆I CC additional supply current A port; VCC(A) = VCC(B) = 3.3 V; AportatVCC(A) − 0.6 V; DIR at VCC(A); B port = open -- 75 µA B port; VCC(A) = VCC(B) = 3.3 V; BportatVCC(B) − 0.6 V; DIR at GND; A port = open -- 75 µA DIR input; VCC(A) = VCC(B) = 3.3 V; AportatVCC(A) or GND; B port = open; DIR at VCC(A) − 0.6 V -- 75 µA Table 7.
