NLV74VHCT541A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 MC74VHCT541A is an advanced high speed CMOS octal bus buffer fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. The MC74VHCT541A is a noninverting, 3-state, buffer/line driver/line receiver. When either OE1 or OE2 is high, the terminal outputs are in the high impedance state. The VHCT inputs are compatible with TTL levels. This device can be used as a level converter for interfacing 3.3V to 5.0V, because it has full 5V CMOS level output swings. The VHCT541A input and output (when disabled) structures provide protection when voltages between 0V and 5.5V are applied, regardless of the supply voltage. These input and output structures help prevent device destruction caused by supply voltage - input/output voltage mismatch, battery backup, hot insertion, etc.
