SN74AHCT244: Pin to pin with SN74AHCT244PWR, and low drive capability

Part Number: SN74AHCT244

Hi team,

Do you have any OCTAL BUFFER/DRIVER that is fully pin to pin with the SN74AHCT244PWR with lower drive capability?

The customer is looking for such a device to reduce overshoot/undershoot without changing the damping resistance on trial board.

Regards,

Yamaguchi

The AHC(T) family already has slow output edges. A possible replacement is the older SN74HCT244, but that one is only a little bit weaker.

Thanks for the suggestion.

Here is the additional information from the customer.

- Vcc=5V

- Input signal = 3.3V

- 3-State output is not required

Regards,

Yamaguchi

Unfortunately, the additional information does not change anything.
