Texas Instruments TA550D
The TL16C550D and the TL16C550DI are speed and operating voltage upgrades (but functional equivalents) of the TL16C550C asynchronous communications element (ACE), which in turn is a functional upgrade of the TL16C450. This relieves the CPU of excessive software overhead by buffering received and transmitted characters.| Part No. | TA550D |
