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 com-
parable 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 con-
sumption 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.
