IDT74LVCH16260A 3.3V CMOS 12-BIT TRI-PORT BUS EXCHANGER WITH 5 VOLT I/O EXTENDED MERCIAL TEMPERATURE RANGE 3.3V CMOS 12-BIT TRI-PORT BUS EXCHANGER WITH 5 VOLT TOLERANT I/O AND BUS-HOLD Features : Typical t SK(0) (Output Skew) < 250ps ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200p F, R = 0) - 0.635mm pitch SSOP, 0.50mm pitch TSSOP and 0.40mm pitch TVSOP packages - Extended mercial range of -40°C to +85°C .. - VCC = 3.3V ±0.3V, Normal Range - VCC = 2.7V to 3.6V, Extended Range - CMOS power levels (0.4µ W typ. static) - All inputs, outputs and I/O are 5 Volt tolerant - Supports hot insertion Drive Features for LVCH16260A: - High Output Drivers: ±24m A - Reduced system switching noise - - IDT74LVCH16260A bus multiplexer/transceiver for use in high-speed microprocessor applications. This bus exchanger supports memory interleaving with latched outputs on the B ports and address multiplexing with latched inputs on the B ports. The LVCH16260A tri-port bus exchanger has three 12-bit ports. Data may be transferred between the A port and either/both of the B ports. The latch enable (LE1B, LE2B, LEA1B and LEA2B) inputs control data storage. When a latch-enable input is high, the latch is transparent. When a latchenable input is low, the data at the input is latched and remains latched until the latch enable input is returned high. Independent output enables (OE1B and OE2B) allow reading from one port while writing to the other port. All pins of the 12-bit Bus Exchanger can be driven from either 3.3V or 5V devices. This feature allows the use of the device as a translator in a mixed 3.3V/5V supply system. The LVCH16260A has been designed with a ±24m A output driver. The driver is capable of driving a moderate to heavy load while maintaining speed performance. The LVCH16260A has “bus-hold” which retains the inputs’ last state whenever the input goes to a high impedance. This prevents floating inputs and eliminates the need...
