IDT74ALVCH16409 3.3V CMOS 9-BIT, 4-PORT UNIVERSAL BUS EXCHANGER INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 9-BIT, 4-PORT UNIVERSAL BUS EXCHANGER WITH 3-STATE OUTPUTS AND BUS-HOLD * 0.5 MICRON CMOS Technology * Typical tSK(o) (Output Skew) < 250ps * ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) * VCC = 3.3V 0.3V, Normal Range * VCC = 2.7V to 3.6V, Extended Range * VCC = 2.5V 0.2V * CMOS power levels (0.4 W typ. static) * Rail-to-Rail output swing for increased noise margin * Available in SSOP, TSSOP, and TVSOP packages IDT74ALVCH16409 FEATURES: DESCRIPTION: DRIVE FEATURES: * High Output Drivers: 24mA * Suitable for heavy loads APPLICATIONS: * 3.3V high speed systems * 3.3V and lower voltage computing systems This 9-bit, 4-port universal bus exchanger is built using advanced dual metal CMOS technology. The ALVCH16409 allows synchronous data exchange between four different buses. Data flow is controlled by the select (SEL0-SEL4) 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 ALVCH16409 has been designed with a 24mA output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance. The ALVCH16409 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.
