HD74LS273P (74LS273)

Description:

The HD74LS273P is an octal D-type flip-flop with eight positive-edge-triggered flip-flops in a single package. Each flip-flop stores a single bit of data, and data inputs (D) are latched into the flip-flops on the rising edge of the clock (CLK) signal. This IC is commonly used in digital electronics for data storage, synchronization, and control applications.

Key Features:

• Octal D-type flip-flop with eight flip-flops in a single package
• Positive-edge-triggered flip-flops: data latched on the rising edge of CLK
• Direct clear (CLR) input for clearing all flip-flops to a logic low state
• Buffered outputs for driving external loads
• Low power consumption: typically ICC = 8 mA at VCC = 5V
• Wide operating voltage range: 4.75V to 5.25V
• TTL compatible inputs and outputs

Technical Specifications:

• Package Type: 20-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): 8 mA (typical) at VCC = 5V
• Operating Temperature Range: 0°C to +70°C

Applications:

• Data storage and synchronization in digital circuits
• Parallel data transfer and buffering
• Address and data bus buffering in microprocessor systems
• Control and timing circuitry in sequential logic applications
• General-purpose digital logic applications
