DUAL 4-INPUT MULTIPLEXER
WITH 3-STATE OUTPUTS
The LSTTL/ MSI SN54/ 74LS253 is a Dual 4-Input Multiplexer with 3-state
outputs. It can select two bits of data from four sources using common select
inputs. The outputs may be individually switched to a high impedance state
with a HIGH on the respective Output Enable (E0) inputs, allowing the outputs
to interface directly with bus oriented systems. It is fabricated with the
Schottky barrier diode process for high speed and is completely compatible
with all Motorola TTL families.
• Schottky Process for High Speed
• Multifunction Capability
• Non-Inverting 3-State Outputs
• Input Clamp Diodes Limit High Speed Termination Effects
