SN74LS194AN (74LS194) register

Description:

The SN74LS194AN is a 4-bit bidirectional universal shift register IC, capable of shifting data in both directions (left and right) based on control inputs. It features a parallel load capability where data can be loaded into the register asynchronously. This IC is commonly used in digital systems for various applications such as data storage, serial-to-parallel conversion, parallel-to-serial conversion, and arithmetic operations involving shifts.

Key Features:

• 4-bit bidirectional shift register
• Parallel load capability for synchronous loading of data
• Shift left (SL), shift right (SR), and shift/load (S/L) control inputs
• Serial (SER) input for serial data entry
• Asynchronous clear (CLR) input for resetting the register
• TTL compatible inputs and outputs
• Edge-triggered for synchronous operation

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
• Output Voltage (VOUT): 0V to VCC
• Input High Voltage (VIH): 2V (min) at VCC = 5V
• Input Low Voltage (VIL): 0.8V (max) at VCC = 5V
• Output Current (IOH, IOL): ±8 mA (max)
• Quiescent Supply Current (ICC): 4 mA (typical) at VCC = 5V
• Operating Temperature Range: 0°C to +70°C

Applications:

• Serial-to-parallel conversion
• Parallel-to-serial conversion
• Data storage and transfer in microprocessor systems
• Arithmetic operations involving shifts (multiplication/division by powers of 2)
• Control and timing applications in digital circuits
