DM74ALS153 Dual 1-of-4 Line Data Selector/Multiplexer
DM74ALS153
Dual 1-of-4 Line Data Selector/Multiplexer
General Description
This Data Selector/Multi plexer contain s full on-chip decoding to select one-of-four data sources as a result of a
unique two-bit binary code at the Select inputs. Each of the
two Data Selector/Multipl e xer c irc uits have the i r own sep arate Data and Strobe inputs and a non-inverting output
buffer. The Select inputs A and B are common to both sections. The Strobe inputs, whe n at the HIGH level, disable
their associated data inputs and force the corresponding
output to the LOW st ate. The Select inp ut buffers inco rporate internal overlap featu res to ensure that select input
changes do not cause invalid output transients.
Features
■ Advanced oxide-isolated, ion-implanted Schottky TTL
process
■ Switching performan ce is gu aranteed over full tempe rature and V
CC
supply range
■ Pin and functional compatible with LS family counterpart
■ Improved output transient handling capability
Ordering Code:
Devices also availab le in Tape and Reel. Specify by appending th e s uffix let t er “X” to the ordering code.
