Other Parts Discussed in Thread: SN74ACT244 , SN74LV244AT , SN74LVC244A Part Number: SN74ACT244 Question type: Development and troubleshooting Support topic: /Product/Development and troubleshooting/ Description of the problem: Short circuit appears between…
The function is the same however since that are t different technologies their voltage and current spcs will be very different. The ALS will have TTL inputs while the LV will have CMOS type inputs. If you need ttl input Levels you can use the SN74LV244AT…
The LVC244 should not operate at 5V Vcc . I would recoment the SN74LV244AT instead. It can operate at with 5V Vcc. It also has TTL inputs which will put the 3.1V input in spec and rise and fall limits are slower which puts them in spec.
