Part Number: SN74LXCH8T245 Other Parts Discussed in Thread: SN74LVC245A , SN74LXC8T245-Q1 Hi Team,
May I ask if the 23pin of SN74LXCH8T245 could be left floating? If pin 23 and 24 connected inside the chip?
Thanks.
Best Regards,

Hey Songzhen,
The SN74LXC8T245-Q1 will be a p2p replacement that includes schmitt-triggers on the inputs so it will have no issue with this application. I recommend they switch to that device.
This device supports more than 40 MHz.
If you need to convert 3.3 V signals to 5 V, you should use a device with TTL-compatible inputs like the SN74AHCT244Q, or an actual level shifter like the SN74LXC8T245-Q1.

Hey Kazuya,
I recommend using the SN74LXC8T245 which is a newer p2p version that has a robust power up. With that device, the answer to Q1 is a definite no.
