Calculate the enable times for the SN74LXC2T45-Q1 using the following formulas:
In a bidirectional application, these enable times provide the maximum delay time from the time the DIR bit is switched until an output is expected. For example, if the SN74LXC2T45-Q1 initially is transmitting from A to B, then the DIR bit is switched; the B port of the device must be disabled (tdis) 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 (tpd). To avoid bus contention, care should be taken to not apply an input signal prior to the output being disabled (tdis maximum).
