74AHC125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 74AHC125; 74AHCT125 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard JESD7-A.

The 74AHC125; 74AHCT125 provides four non-inverting buffer/line drivers with 3-state outputs. The 3-state outputs (nY) are controlled by the output enable input (nOE). A HIGH at nOE causes the outputs to assume a high-impedance OFF-state.

The 74AHC125; 74AHCT125 is identical to the 74AHC126; 74AHCT126 but has active LOW enable inputs.
