MM74HCT540 - MM74HCT541 Inverting Octal 3-STATE Buffer - Octal 3-STATE Buffer February 1984 Revised February 1999 MM74HCT540 - MM74HCT541 Inverting Octal 3-STATE Buffer - Octal 3-STATE Buffer 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 parable to low power Schottky devices, while retaining the low power consumption of CMOS. Both devices are TTL input patible and have a fanout of 15 LS-TTL equivalent inputs. MM74HCT devices are intended to interface between TTL and NMOS ponents 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. The MM74HCT540 is an inverting buffer and the MM74HCT541 is a non-inverting buffer. The 3-STATE control gate operates as a two-input NOR such that if either G1 or G2 are HIGH, all eight outputs are in the high-impedance state. In order to enhance PC board layout, the MM74HCT540 and MM74HCT541 offers a pinout having inputs and outputs on opposite sides of the package. All inputs are protected from damage due to static discharge by diodes to VCC and ground.
