The 74HC273AP is an octal D-type flip-flop with reset, manufactured by Toshiba (TOS).

Key Specifications:

• Logic Family: 74HC (High-Speed CMOS)
• Function: Octal D-type flip-flop with reset (positive-edge triggered)
• Number of Flip-Flops: 8
• Input Type: CMOS
• Output Type: CMOS
• Supply Voltage Range: 2V to 6V
• High-Level Input Voltage (Min): 3.15V @ 4.5V supply
• Low-Level Input Voltage (Max): 1.35V @ 4.5V supply
• Propagation Delay: 18ns (typical) @ 5V supply
• Operating Temperature Range: -40°C to +85°C
• Package: DIP-20 (Plastic Dual In-Line Package)

Descriptions:

The 74HC273AP features eight D-type flip-flops with a common clock (CP) and master reset (MR). On the positive clock edge, data at the D inputs is transferred to the Q outputs. A low level on the MR pin clears all flip-flops asynchronously.

Features:

• High-Speed Operation: Optimized for fast switching applications
• Wide Operating Voltage: Supports 2V to 6V
• Low Power Consumption: CMOS technology ensures low static power dissipation
• Asynchronous Reset: Master reset clears all outputs independently of the clock
• High Noise Immunity: Standard CMOS input/output levels
• Pin-Compatible with 74LS273: Can replace LS-type devices in many applications

This IC is commonly used in registers, counters, and data storage applications.
