DESCRIPTION
The
M54/74HCT240PU,
HCT241PU
and
HCT244PU are high speed CMOS OCTAL BUS
BUFFERs fabricated
in silicon gate C
2MOS
technology.
They have the same high speed performance of their
non-PU counterpart, plus a unique input topology
which incorporates a constant current source for
each data input. This results is in a small IIL (-150
A
Typ.) wich can fix any data input in the HIGH Logic
Level when it is left floating, thus eliminating the need
of external pull-up resistor network.
This feature makes these devices particularly
suitable in all applications where a data bus needs to
be interfaced to manual controls like: rotary selectors,
keyboards,
dip-switches, etc. The inputs are
compatible with TTL, NMOS and CMOS output
voltage levels. They achieve the high speed
operation
similar
to
equivalent
LSTTL while
maintaining the CMOS low power dissipation.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
