The PI74AVC+16652 is a 16-bit bus transceiver and register designed for low 1.65V to 3.6V VCC operation. It consists of D-type flip-flops and control circuitry arranged for multiplexed transmission of data directly from the data bus or from the internal storage registers. The device can be used as two 8-bit transceivers or one 16-bit transceiver. Complementary Output Enable (OEAB and OEBA) inputs are provided to control the transceiver functions. Select Control (SAB and SBA) inputs are provided to select whether real-time or stored data is transferred. A low input level selects real-time data, and a high input level selects stored data. Circuitry used for Select Control eliminates the typical decoding glitch that occurs in a multiplexer during the transition between stored and real-time data. Data on the A or B bus, or both, can be stored in the internal D flipflops by low-to-high transitions at the appropriate clock (CLKAB or CLKBA) inputs regardless of the levels on the Select Control or Output Enable inputs. When SAB and SBA are in the real-time transfer mode, it also is possible to store data without using the internal D-type flip-lops by simultaneously enabling OEAB and OEBA. In this configuration, each output reinforces its input. Thus, when all other data sources to the two sets of bus lines are in the high-impedance state, each set of bus lines remains at its last level configuration. To ensure the high-impedance state during power up or power down, OEBA should be tied to VCC through a pull-up resistor and OEAB should be tied to GND through a pull-down resistor; the minimum value of the resistor is determined by the current-sinking current sourcing capability of the driver. PI74AVC+16652 is designed for low-voltage operation, VCC = 1.65V to 3.6V True ±24mA Balanced Drive @ 3.3V IOFF supports partial power-down operation 3.6V I/O Tolerant Inputs and Outputs All outputs contain a patented DDC (Dynamic DriveControl) circuit that reduces noise without degrading propagation delay.

Load Circuit and Voltage Waveforms Notes: A. CL includes probe and jig capacitance. B. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control. Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control. C.
