features
o selects one-of-sixteen (or one-of-eight) data
sources
o serves as a five-variable~function generator
(ITT54150.ITT74150)
o performs parallel-to-serial conversion
o permits multiplexing from N lines to 1 line
o input-clamping diodes simplify system design
o typical propagation delay times:
through 4 select levels - 28 ns
through 3 select levels - 20 ns
data input to output -10 n s
o high fan-out. low impedance. totem-pole
outputs
o fully compatible with TTL. DTL and other
MSI circuits
Each of these monolithic. data selectors/multiplexers
contain inverter/drivers to supply
fully complementary. on-chip. binary decoding data
selection to the AND-OR-INVERT gate. The ITT-
54151 /ITT7 4151 features complementary outputs
whereas the ITT54150/ITT74150 has inverted outputs
only. The circuits are provided with a strobeinput
which. when taken to a logical O. enables the
function of these multiplexers.
These data selectors/multiplexers are fully compatible
for use with other TTL or DTL circuits. Each input
represents only one normalized Series 54174
load. and full fan-out to 10 normalized Series
54174 loads is available from each of the outputs
in the logical 0 state. A fan-out to 20 normalized
Series 54174 loads is provided in the logical 1 state
to facilitate connection of unused inputs to used
inputs. Typical power dissipations are:
ITT541 50/ITT74150 - 200 milliwatts
ITT541 51 /ITT74151 - 145 milliwatts
These data selectors feature Series 54H/74H circuitry
for the OR function. This is done to minimize
the capacitive effects of paralleling the phasesplitter
transistors and thus reduce the propagation
delay time. The ITT54150. and ITT541 51. are characterized
for operation over the full military temperature
range of - 55° C to 125° C; the ITT7 4150.
and ITT74151 are characterized for operation from
O°C to 70°C.
