Part Description: 74LS253


Part Details:

SN54/74LS253 DUAL 4-INPUT MULTIPLEXERWITH 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 selectinputs. The outputs may be individually switched to a high impedance state DUAL 4-INPUT MULTIPLEXER with a HIGH on the respective Output Enable (E0) inputs, allowing the outputs WITH 3-STATE OUTPUTS to interface directly with bus oriented systems. It is fabricated with theSchottky barrier diode process for high speed and is completely compatible LOW POWER SCHOTTKY 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 J SUFFIX CERAMIC CASE 620-09 16 CONNECTION DIAGRAM DIP (TOP VIEW) 1 VCC E0b S0 I3b I2b I I 1b 0b Zb 16 15 14 13 12 11 10 9 N SUFFIX NOTE: PLASTIC The Flatpak version CASE 648-08 16 has the same pinouts(Connection Diagram) as 1 the Dual In-Line Package. 1 2 3 4 5 6 7 8 D SUFFIX
