| Q. |
What is unique about TTL devices such as the 74SXX? |
| A. | these devices use schottky transistors and diodes to prevent them from going into saturation; this results in faster turn-on and turn-off times, which translates into higher frequency operation. |
| B. | the gate transistors are silicon (s), and the gates therefore have lower values of leakage current. |
| C. | the s denotes the fact that a single gate is present in the ic rather than the usual package of 2–6 gates. |
| D. | the s denotes a slow version of the device, which is a consequen ce of its higher power rating. |
| Answer» A. these devices use schottky transistors and diodes to prevent them from going into saturation; this results in faster turn-on and turn-off times, which translates into higher frequency operation. | |
