The CY74FCT163543 is a 16-bit, high-speed, low power latched transceiver that is organized as two independent 8-bit D-type latched transceivers, containing two sets of eight D-type latches with separate Latch Enable (LEAB, LEAB) and Output Enable (OEAB, OEAB) controls for each set to permit independent control of inputting and outputting in either direction of data flow. For data flow from A to B, for example, the A-to-B input Enable (CEAB) must be LOW in order to enter data from A or to take data from B, as indicated in the truth table. With CAEB LOW, a LOW signal on the A-to-B Latch Enable (LEAB) makes the A-to-B latches transparent; a subsequent LOW-to-HIGH transition of the LEAB signal puts the A latches in the storage mode and their outputs no longer follow the A inputs. With CEAB and OEAB both LOW, the three-state B output buffers are active and reflect the data present at the output of the A latches. Control of data from B to A is similar, but uses CEAB, LEAB, and OEAB inputs. The CY74FCT163543 has 24-mA balanced output drivers with current limiting resistors in the outputs. This reduces the need for external terminating resistors and provides for minimal undershoot and reduced ground bounce. The inputs and outputs are capable of being driven by 5.0V buses, allowing them to be used in mixed voltage systems as translators. The outputs are also designed with a power off disable feature enabling them to be used in applications requiring live insertion. Flow-through pinout and small shrink packaging simplify board design.
