Q. What is unique about TTL devices such as the 74S00? (Solved)
1. the gate transistors are silicon (s), and the gates therefore have lower values of leakage current.
2. the s denotes the fact that a single gate is present in the ic rather than the usual package of 2–6 gates.
3. the s denotes a slow version of the device, which is a consequence of its higherpower rating.
4. the devices use schottky transistors anddiodes to prevent them from going into saturation; this results in faster turn on and turn off times, which translates intohigher frequency operation.
- d. the devices use schottky transistors anddiodes to prevent them from going into saturation; this results in faster turn on and turn off times, which translates intohigher frequency operation.
