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.
Ordering Information
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering number.
