The HD74HC74FPEL-E is a dual D-type flip-flop with set and reset inputs, manufactured by Renesas Electronics America. This high-speed CMOS device utilizes advanced silicon-gate CMOS technology to achieve the high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining low power dissipation. It contains two independent flip-flops, each with individual set (SD), reset (RD), clock (CP), and data (D) inputs; Q and Q outputs are also provided.

Applications

• Registers
• Counters
• Shift registers
• Memory elements
• Control circuits

Features

• High-speed operation: fMAX = 63 MHz (typ.) at VCC = 5V
• Low power dissipation: ICC = 4 μA (max.) at Ta = 25°C
• High noise immunity: VNIH = VNIL = 28 % VCC (min.)
• Output drive capability: 10 LSTTL loads
• Symmetrical output impedance: |IOH| = IOL = 4 mA (min.)
• Wide operating voltage range: VCC = 2 to 6 V
• Pin and function compatible with 74LS74

Benefits

• Improved system performance due to high-speed operation.
• Reduced power consumption, leading to energy efficiency.
• Enhanced noise immunity, providing more reliable operation in noisy environments.
• Direct interface with TTL circuits.
• Flexible operating voltage range suitable for various applications.
• Easy replacement of existing 74LS74 devices.

Additional Details

The HD74HC74FPEL-E features asynchronous set and reset capabilities, meaning the outputs can be set or reset independently of the clock signal. A low level on the SD input sets the Q output HIGH, and a low level on the RD input resets the Q output LOW. Simultaneous LOW levels on both SD and RD are not allowed. The device is supplied in a 14-pin SOP package.
