B and a LOW on DIR allows transmission from B to A.
GND level, both A port and B port are in the high-impedance OFF-state.
The input circuit of the data I/O is always active.
When either VCC(A) or VCC(B) is at GND level, the device goes into suspend mode.
The minimum input voltage ratings and output voltage ratings may be exceeded if the input and output current ratings are observed.
VCCO is the supply voltage associated with the output port.
VCCO + 0.5 V should not exceed 6.5 V.
For SC-88 package: above 87.5 C the value of Ptot derates linearly with 4.0 mW/K.
VCCI is the supply voltage associated with the input port.
VCCI is the supply voltage associated with the data input port.
To guarantee the node switches, an external driver must source/sink at least IBHLO/IBHHO when the input is in the range VIL to VIH.
For non-bus hold parts only (74LVC1T45-Q100).
fi = 10 MHz; VI = GND to VCC; tr = tf = 1 ns; CL = 0 pF; RL =  .
Measurement points are given in Table 14.
VOL and VOH are typical output voltage levels that occur with the output load.
Test data is given in Table 15.
VEXT = External voltage for measuring switching times.
(1) VCC(B) = 1.2 V.
(2) VCC(B) = 1.5 V.
(3) VCC(B) = 1.8 V.
(4) VCC(B) = 2.5 V.
(5) VCC(B) = 3.3 V.
(6) VCC(B) = 5.0 V.
being used in a unidirectional logic level-shifting application.
Pull-up or pull-down only needed for 74LVC1T45-Q100.
system-2 and then from system-2 to system-1.
system-2 is getting ready to send data to system-1.
DIR bit is set LOW. I/O-1 and I/O-2 are still disabled.
The bus-line state depends on bus hold.
the corresponding A port after the specified propagation delay.
