It is ideal for 1.65 to 3.6 V applications; it can be interfaced to 3.6V signal enviroment for both inputs and outputs. LFBGA96 (Top and Bottom view) ORDER CODES PACKAGE TRAY T&R LFBGA96 74ALVCH32245LB 74ALVCH32245LBR This IC is intended for two-ways asynchronous communication between data buses: the direction of data trasmission is determined by DIR input. Any nG contol output governs eight BUS TRANSCEIVERS. Output Enable input (nG) tied together gives full 32-bit operation. When nG is LOW, the output are enabled. When nG is HIGH, the output are in high impedance state so that the buses are effectively isolated. Bus hold on data inputs is provided in order to eliminate the need for external pull-up or pull-down resistor. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
