Hi,
The FIFO part SN74ACT7881 suffices all our design requirements. But except the factor that its VCC is high (4.5V to 5V). The MCU we are interfacing with this FIFO works at IO level of 3.3V.
Hence we would like to confirm below points:
1. Can we provide 5V to VCC but interface this FIFO with 3.3V IO devices? Will it work?
2. If answer for 1st question is NO, then we are not interested in going for Translator ICs as it might affect our throughputs. Hence do you suggest any FIFO chip that has all features (FULL, EMPTY, HALF FULL/EMPTY), ALMOST FULL/EMPTY) similar to SN74ACT7881 with VCC and IO Voltages at 3.3V level.
Regards,
Vijetha
