I need a bus driver for 3,3V to 5V conversion of a 8 bit parallel bus (10MHz) with 50cm length.
Are components available with defined rising and falling edge of about 20ns to reduce reflections?
Thanks.
Best regards
Manuel
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 several improved features. http://focus.ti.com/lit/ds/symlink/sn74lvc8t245.pdf.
