Part Number: SN74LS640 Hi, support team
About SN74LS640-1N and SN74ALS640−1B's AC characteristic: Could you tell me the time from DIR H→L ( L→H ) to A/B data direction reversal?
About SN74LS125AN's AC characteristic: There‘s no AC…
The only way to make a TTL output work with a TXB input is to use a supply of about 2.4 V, but then the output voltage might be too low. You should use a TXS translator instead.
What happens with slowly changing input voltages is shown in figure 2 of…
