74LVC2245ADB数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

Octal transceiver with direction pin - The 74LVC2245A is a octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. A send/receive (DIR) input controls direction, and an output enable (OE) input makes easy cascading possible. Pin OE controls the outputs so that the buses are effectively isolated. It is a high-performance, low-power, low-voltage, Si-gate CMOS device and superior to most advanced CMOS compatible TTL families. The device is designed with 30 Ω series termination resistors in both HIGH and LOW output stages to reduce line noise. Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied to the outputs. These features allow the use of these devices as translators in mixed 3.3 V and 5 V applications.
