54150/DM54150/DM74150,

54151A/DM54151A/DM74151A

Data Selectors/Multiplexers

General Description

These data selectors/multiplexers contain full on-chip de-

coding to select the desired data source. The 150 selects

one-of-sixteen data sources; the 151A selects one-of-eight

data sources. The 150 and 151A have a strobe input which

must be at a low logic level to enable these devices. A high

level at the strobe forces the W output high and the Y output

(as applicable) low.

The 151A features complementary W and Y outputs, where-

as the 150 has an inverted (W) output only.

The 151A incorporates address buffers which have sym-

metrical propagation delay times through the complementa-

ry paths. This reduces the possibility of transients occurring

at the output(s) due to changes made at the select inputs,

even when the 151A outputs are enabled (i.e., strobe low).

Note:

The ‘‘Absolute Maximum Ratings’’ are those values

beyond which the safety of the device cannot be guaran-

teed. The device should not be operated at these limits. The

parametric values defined in the ‘‘Electrical Characteristics’’

table are not guaranteed at the absolute maximum ratings.

The ‘‘Recommended Operating Conditions’’ table will define

the conditions for actual device operation.
