MM74HC541MTC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

General Description

The MM74HC540 and MM74HC541 3-STATE buffers utilize advanced silicon-gate CMOS technology. They possess high drive current outputs which enable high speed operation even when driving large bus capacitances. These circuits achieve speeds comparable to low power Schottky devices, while retaining the advantage of CMOS circuitry, i.e., high noise immunity, and low power consumption. Both devices have a fanout of 15 LS-TTL equivalent inputs.

Features

■ Typical propagation delay: 12 ns

■ 3-STATE outputs for connection to system buses

■ Wide power supply range: 2–6V

■ Low quiescent current: 80 PA maximum (74HC Series)

■ Output current: 6 mA
