74HC541D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

1. General description

The 74HC541; 74HCT541 is an octal non-inverting buffer/line driver with 3-state outputs. The

device features two output enables (OE1 and OE2). A HIGH on OEn causes the outputs to assume

a high-impedance OFF-state. Inputs include clamp diodes that enable the use of current limiting

resistors to interface inputs to voltages in excess of VCC.
