14.3 Power-up considerations
14.4 Enable times
The device is designed such that no special power-up sequence is required other than
GND being applied first.
Table 18.
Calculate the enable times for the 74LVC1T45; 74LVCH1T45 using the following formulas:
In a bidirectional application, these enable times provide the maximum delay from the
time the DIR bit is switched until an output is expected. For example, if the 74LVC1T45;
74LVCH1T45 initially is transmitting from A to B, then the DIR bit is switched, the B port of
the device must be disabled before presenting it with an input. After the B port has been
disabled, an input signal applied to it appears on the corresponding A port after the
specified propagation delay.
