74LCX16245G

低电压16位双向收发器，具有5V容限输入和输出 Low Voltage 16-Bit Bidirectional Transceiver with 5V Tolerant Inputs and Outputs

General Description

The LCX16245 contains sixteen non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus ori ented applications. The device is designed for low voltage 2.5V or 3.3V VCCapplications with capability of interfac ing to a 5V signal environment. The device is byte con

trolled. Each byte has separate control inputs which could be shorted together for full 16-bit operation. The T/Rinputs determine the direction of data flow through the device. The OEinputs disable both the A and B ports by placing them in a high impedance state. The LCX16245 is fabricated with an advanced CMOS tech nology to achieve high speed operation while maintaining CMOS low power dissipation.
