DESCRIPTION
The 74LVC541A is a lo w voltage CMOS OCTAL
BUS BUFFER (3-STATE) fabricated with
sub-micron silicon gate and double-layer metal
wiring C

MOS tecnology. It is ideal fo r 1.6 5 to 3. 6
V
CC
operations and low power and low noise
applications.
The 3 STATE control gate opera tes as two input
AND 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
74LVC541A offers a pinout having inputs and
outputs on opposite sides of the package.
This device is designed to interface di rectly High
Speed CMOS systems with TTL and NMOS
components.
It has more speed performance at 3.3V than 5V
AC/ACT family, combined with a lower power
consumption.
All inputs are equipped with protection circuits
against static discharge, giving them 2KV ESD
immunity and transient excess voltage.
