缓冲器和线路驱动器 Inv Oct 3-STATE Buf
General Description
The MM74HCT540 and MM74HCT541 3-STATE buffers utilize advanced silicon-gate CMOS technology and are general purpose high speed inverting and non-inverting buffers. 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 low power consumption of CMOS. Both devices are TTL input compatible and have a fanout of 15 LS-TTL equivalent inputs.
MM74HCT devices are intended to interface between TTL and NMOS components and standard CMOS devices. These parts are also plug-in replacements for LS-TTL devices and can be used to reduce power consumption in existing designs.
