DESCRIPTION:
This 9-bit, 4-port universal bus exchanger is built using advanced dual metal CMOS technology. The ALVCHR16409 allows synchronous data exchange between four different buses. Data flow is controlled by the select (SEL0SEL4) inputs. A data-flow state is stored on the rising edge of the clock (CLK) input if the select-enable (SELEN) input is low. Once a data-flow state has been established, data is stored in the flip-flop on the rising edge of CLK if SELEN is high. The data-flow control logic is designed to allow glitch-free data transmission. When preset (PRE) transitions high, the outputs are disabled immediately without waiting for a clock pulse. To leave the high-impedance state, both PRE and SELEN must be low and a clock pulse must be applied. The ALVCHR16409 has been designed with a ±24mA output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance. The ALVCHR16409 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.
APPLICATIONS:
· 3.3V High Speed Systems · 3.3V and lower voltage computing systems
