SN74HC7032: Does "tt" parameter in SN74HC7032 switching characteristics table mean both rising time (tr) and falling time (tf) of Y terminal?

Part Number: SN74HC7032
Other Parts Discussed in Thread: SN74LVC2G00

 Hello guys,

 One of our customers is considering using SN74HC7032 for their brand new products. The customer has the following questions about the device. Could you please give me you answers or comments to the questions?

1. Does "tt" parameter in SN74HC7032 switching characteristics table mean both rising time (tr) and falling time (tf) of Y terminal?

2. If SN74HC7032 output (Yn) is connected to SN74LVC2g00 input (An or Bn), is it no problem because HC7032 output rise/fall time is 19ns (Max at 4.5V) and SN74LVC2g00 input delta t/delta V is requiered 5ns as the maximum, that means tt(ns) > delta t/delta V?

 Your answers would be appreciated.

 Best regards,

 Kazuya Nakai.
