The device is designed for serial interface to a microprocessor or peripheral via a 3-state output with three inputs [including I/O CLOCK, CS (chip select), and ADDRESS INPUT]. The TLC542 allows high-speed data transfers and sample rates of up to 40,000 samples per second. In addition to the high-speed converter and versatile control logic, an on-chip 12-channel analog multiplexer can sample any one of 11 inputs or an internal self-test voltage, and the sample and hold is started under microprocessor control. At the end of conversion, the end-ofconversion (EOC) output pin goes high to indicate that conversion is complete. The converter incorporated in the TLC542 features differential high-impedance reference inputs that facilitate ratiometric conversion, scaling, and isolation of analog circuitry from logic and supply noises. A switchedcapacitor design allows low-error ( 0.5 LSB) conversion in 20 s over the full operating temperature range. The TLC542C is characterized for operation from 0C to 70C and the TLC542I is characterized for operation from - 40C to 85C.

The device includes such functions as analog multiplexer, sample and hold, 8-bit A/D converter, data and control registers, and control logic. Three control inputs (I/O CLOCK, CS (chip select), and ADDRESS INPUT) are included for flexibility and access speed. These control inputs and a TTL-compatible 3-state output are intended for serial communications with a microprocessor or microcomputer. With judicious interface timing, the TLC542 can complete a conversion in 20 s, while complete input-conversion-output cycles can be repeated every 40 s. Furthermore, this fast conversion can be executed on any of 11 inputs or its built-in self-test and in any order desired by the controlling processor. When CS is high, the DATA OUT terminal is in a 3-state condition, and the ADDRESS INPUT and I/O CLOCK terminals are disabled. When additional TLC542 devices are used, this feature allows each of these terminals, with the exception of the CS terminal, to share a control logic point with their counterpart terminals on additional A/D devices. Thus, this feature minimizes the control logic terminals required when using multiple A/D devices. The control sequence is designed to minimize the time and effort required to initiate conversion and obtain the conversion result. A normal control sequence is as follows: 1. CS is brought low. To minimize errors caused by noise at the CS input, the internal circuitry waits for two rising edges and then a falling edge of the internal system clock before recognizing the low CS transition. The MSB of the result of the previous conversion automatically appears on the DATA OUT terminal. 2. On the first four rising edges of the I/O CLOCK, a new positive-logic multiplexer address is shifted in, with the MSB of this address shifted first. The negative edges of these four I/O CLOCK pulses shift out the second, third, fourth, and fifth most significant bits of the result of the previous conversion. The on-chip sample and hold begins sampling the newly addressed analog input after the fourth falling edge of the I/O CLOCK. The sampling operation basically involves charging the internal capacitors to the level of the analog input voltage. 3. Three clock cycles are applied to the I/O CLOCK terminal and the sixth, seventh, and eighth conversion bits are shifted out on the negative edges of these clock cycles. 4. The final eighth clock cycle is applied to the I/O CLOCK terminal. The falling edge of this clock cycle initiates a 12-system clock ( 12 s) additional sampling period while the output is in the high-impedance state. Conversion is then performed during the next 20 s. After this final I/O CLOCK cycle, CS must go high or the I/O CLOCK must remain low for at least 20 s to allow for the conversion function. CS can be kept low during periods of multiple conversion. If CS is taken high, it must remain high until the end of conversion. Otherwise, a valid falling edge of CS causes a reset condition, which aborts the conversion process. A new conversion may be started and the ongoing conversion simultaneously aborted by performing steps 1 through 4 before the 20-s conversion time has elapsed. Such action yields the conversion result of the previous conversion and not the ongoing conversion. The end-of-conversion (EOC) output goes low on the negative edge of the eighth I/O CLOCK. The subsequent low-to-high transition of EOC indicates the A/D conversion is complete and the conversion is ready for transfer.
