74 LS 151 - 8-Input Multiplexer TTL Logic IC

• Model Number: 74LS151 HLF
• Logic Type: Multiplexer
• Number of Channels: 8
• Control Inputs: 3-bit select lines (S0, S1, S2)
• Output Type: True (Z) and Complement (Z̅)
• Supply Voltage (Vcc): 4.75V - 5.25V
• Input High Voltage (VIH): Min 2V
• Input Low Voltage (VIL): Max 0.8V
• Output High Voltage (VOH): Min 2.7V
• Output Low Voltage (VOL): Max 0.5V
• Propagation Delay: Approx. 15ns
• Operating Temperature: 0°C to +70°C
• Package Type: DIP-16 (Dual In-line Package)

• Pin Configuration: Connect the data inputs (I0-I7) to the corresponding signals, and use the select lines (S0, S1, S2) to control which input is routed to the output.
• Power Supply: Connect Vcc (Pin 16) to +5V and GND (Pin 8) to ground.
• Enable Input (E): Set to LOW to activate the multiplexer; setting HIGH disables the output.
• Output Handling: The selected input is transmitted to Z, while the complement is available at Z̅.
