74AHCT07APW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

The 74AHCT07A is a hex buffer with open-drain outputs. The outputs are open-drain and can be connected to other open-drain outputs to implement active-LOW wired-OR or active-HIGH wired-AND functions.
Designed to operate over a VCC range from 4.5 V to 5.5 V, the inputs are TTL compatible, which allows the device to be used to translate from 3.3 V to 5 V. Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.
This device is fully specified for partial Power-down applications using IOFF . The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
