IDT74LVCH32245A 3.3V CMOS 32-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE IDT74LVCH32245A 3.3V CMOS 32-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS, 5 VOLT TOLERANT I/O, BUS-HOLD - Typical t SK(o) (Output Skew) < 250ps - ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200p F, R = 0) - 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 5V tolerant - Supports hot insertion - Available in 96-ball LFBGA package Features : DESCRIPTION: DRIVE Features : - Balanced Output Drivers: ±24m A - Reduced system switching noise APPLICATIONS: This 32-bit bus transceiver is built using advanced dual metal CMOS technology. This high-speed, low power transceiver is ideal for asynchronous munication between two busses (A and B). The Direction and Output Enable controls are designed to operate the device as either four independent 8-bit transceivers or one 32-bit transceiver. The direction control pins (DIR) control the direction of data flow. The output enable pins (OE) override the direction control and disable both ports. All inputs are designed with hysteresis for improved noise margin. All pins can be driven from either 3.3V or 5V devices. This feature allows the use of this device as a translator in a mixed 3.3V/5V supply system. The LVCH32245A has been designed with a ±24m A output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance The LVCH32245A 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 for pull-up/down resistors. - 5V and 3.3V mixed voltage systems - Data munication and telemunication systems FUNCTIONAL BLOCK DIAGRAM A3 A4 J3 J4 1DIR 3DIR 1OE 3OE 1A1 A5 A2 3A1...
