SN74LS157N (74LS157)

Description:

The SN74LS157N IC contains four separate 2-input multiplexers, labeled as MUX1 to MUX4, with two data inputs (A and B), one select input (S), and one output (Y) per multiplexer. Multiplexers allow digital circuits to select between multiple input signals and choose one for output based on the control signal (select input). This IC is designed for high-speed operation and low power consumption, making it suitable for various digital logic applications requiring signal routing and selection.

Key Features:

• Quad 2-input multiplexers
• Low-power Schottky TTL technology
• Wide operating voltage range: 4.75V to 5.25V
• Typical propagation delay: 18 ns at VCC = 5V, CL = 15 pF
• High output drive capability: ±8 mA at VCC = 5V
• Direct compatibility with TTL input levels
• Schmitt-trigger inputs for improved noise immunity

Technical Specifications:

• Package Type: 16-pin DIP (Dual In-line Package)
• Supply Voltage (VCC): 4.75V to 5.25V
• Input Voltage (VIN): 0V to VCC
