The ALVCH16652 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 flip-flops by low-to-high transition 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-flops 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. The ALVCH16652 has been designed with a ±24mA output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance. The ALVCH16652 has “bus-hold” which retains the inputs’ last state whenever the input bus goes to a high impedance. This prevents floating inputs and eliminates the need for pull-up/down resistors. DRIVE FEATURES: • High Output Drivers: ±24mA • Suitable for heavy loads APPLICATIONS: • 3.3V high speed systems • 3.3V and lower voltage computing systems FUNCTIONAL BLOCK DIAGRAM 1OEBA 56 2OEBA 29 1OEAB 1 2OEAB 28 1CLKBA 55 2CLKBA 30 1SBA 54 2SBA 31 1CLKAB 2 2CLKAB 27 2SAB 26 1SAB 3 B REG B REG D D C 1A1 5 C 52 A REG 1B1 D 2A1 15 42 A REG 2B1 D C C TO 7 OTHER CHANNELS TO 7 OTHER CHANNELS The IDT logo is a registered trademark of Integrated Device Technology, Inc.

Data input functions are always enabled, i.e. data at the bus pins will be stored on every LOW-to-HIGH transition on the clock inputs. 3. Select control = L: clocks can occur simultaneously. Select control = H: clocks must be staggered to load both registers.
