TC4469中文资料Quad 1.2 A MOSFET Gate Driver数据手册Microchip规格书

描述 Description

The TC446x family of four-output CMOS buffer/gate drivers are an expansion from our earlier single- and dual-output gate drivers. Each gate driver has been equipped with a two-input logic gate for added flexibility. The TC446x gate drivers can source up to 250 mA into loads referenced to ground. Heavily loaded clock lines, coaxial cables, and piezoelectric transducers can all be easily driven with the 446x series gate drivers. The only limitation on loading is that total power dissipation in the IC must be kept within the power dissipation limits of the package. The TC446X series will not latch under any conditions within their power and voltage ratings. They are not subject to damage when up to 5 V of noise spiking (either polarity) occurs on the ground line. They can accept up to half an amp of inductive kickback current (either polarity) into their outputs without damage or logic upset. In addition, all terminals are protected against ESD to at least 2 kV.
