74LCX2244MSA集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

General Description

The LCX2244 contains eight non-inverting buffers with 3-STATE outputs. The device may be employed as a memory address driver, clock driver and bus-oriented transmitter/receiver. The LCX2244 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment. The 26Ω series resistors help reduce output overshoot and undershoot.
