Inverting Octal 3-STATE Buffer Octal 3-STATE Buffer
General Description
The MM74HC540 and MM74HC541 3-STATE buffers uti-
lize advanced silicon-gate CMOS technology. They pos-
sess 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 consump-
tion. Both devices have a fanout of 15 LS-TTL equivalent
inputs.
The
MM74HC540
is
an
inverting
buffer
and
the
MM74HC541 is a non-inverting buffer. The 3-STATE con-
trol gate operates as a two-input NOR such that if either G1
or G2 are HIGH, all eight outputs are in the high-imped-
ance state.
In order to enhance PC board layout, the MM74HC540 and
MM74HC541 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.
Features
s Typical propagation delay: 12 ns
s 3-STATE outputs for connection to system buses
s Wide power supply range: 2–6V
s Low quiescent current: 80
PA maximum (74HC Series)
s Output current: 6 mA
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
