FAST AND LS TTL DATA
DUAL 4-INPUT MULTIPLEXER
The LSTTL/MSI SN54/74LS153 is a very high speed Dual 4-Input
Multiplexer with common select inputs and individual enable inputs for each
section. It can select two bits of data from four sources. The two buffered
outputs present data in the true (non-inverted) form. In addition to multiplexer
operation, the LS153 can generate any two functions of three variables. The
LS153 is fabricated with the Schottky barrier diode process for high speed and
is completely compatible with all Motorola TTL families.
• Multifunction Capability
• Non-Inverting Outputs
• Separate Enable for Each Multiplexer
• Input Clamp Diodes Limit High Speed Termination Effects
