Part Number: SN74ABT2244A Other Parts Discussed in Thread: SN74LV8151 , SN74HCT244 The SN74ABT2244A has a typical hysteresis specification of 100mV at 25C form the SCBS106E datasheet. This is specified along with the output specifications rather than the…
Hey Mike,
You could use an SN74HCT244 - which is an octal buffer w/ 3-state outputs -- this has the added benefit of working with 3.3V inputs while the supply is set to 5V.
One thing I would recommend keeping an eye on is the maximum allowed current…
Are you using the TI version of 74ALVC244 (ie SN74ALVC244)?
Our SN74HCT244 has lower current drive but the same functionality that might also fix the problem.
Hello Manuel
Here are some options.
SN74HCT244. With 5V VCC the TTL input will except 3.3V Vih. The advanage to this is the edges will be slow. http://focus.ti.com/lit/ds/symlink/sn74hct244.pdf
SN74LVC8T245 This part is a duel voltage translator with…
