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

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.
