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

DESCRIPTION

The 74AHC/AHCT125 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard No. 7A.

The 74AHC/AHCT125 are 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 n causes the outputs to assume a HIGH-impedance OFF-state.

The ‘125’ is identical to the ‘126’ but has active LOW enable inputs.
