SEMICONDUCTORS
BCD TO DECIMAL DECODER
The ITT380 and ITT381 decode standard BCD
(1-2-4-8) inputs to produce a low state on one
of the ten open collector outputs. Internal design
insures that no ambiguous outputs are
produced, turning off all outputs when addressed
by input codes for 10-1S. The ITT380
is intended to drive small lamps directly or
can' be used with various interface buffering
schemes. The ITT381 is identical to the ITT380
with the exception of its output ratings and is
intended for use as an internal circuit element.
