74AVC1T1022GU数据手册集成电路（IC）的时钟缓冲器驱动器规格书PDF

描述 Description

The 74AVC1T1022 is a translating 1-to-4 fan-out buffer suitable for use in clock distribution. It has dual supplies (VCC(A) and VCC(B)) for voltage translation. It also has a data input (A), four data outputs (1Yn and 2Yn) and an output enable input (OE). VCC(A) and VCC(B) can be independently supplied at any voltage between 0.8 V and 3.6 V. It makes the device suitable for low voltage translation between any of the following voltages: 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V. The levels of A, OE and 1Yn are referenced to VCC(A), outputs 2Yn are referenced to VCC(B). This supply configuration ensures that two of the fanned out signals can be used in level shifting. A HIGH on OE causes all outputs to be pulled LOW via pull-down resistors, a LOW on OE disconnects the pull-down resistors and enables all outputs.
Schmitt trigger action at all inputs makes the circuit tolerant for slower input rise and fall time.
The IOFF circuitry disables the output, preventing any damaging backflow current through the device when it is powered down.
