The GD74HCT174 is a high-speed silicon-gate CMOS device and is pin-compatible with low power Schottky TTL (LSTTL). It is a hex D-type flip-flop with a common clock and a common clear input, manufactured by LG. Information at the D inputs is transferred to the Q outputs on the positive-going edge of the clock pulse. All six flip-flops are controlled by a common clock (CP) and a common clear (CLR) input. The device is designed for use in high-speed applications where data storage and transfer are required.

Applications:

• Shift registers
• Buffer storage
• Data synchronization
• Control registers
• Memory address latches

Features:

• High Speed Operation: tpd = 16ns (typ.) at VCC = 5V
• Low Power Dissipation: ICC = 4uA (max.) at TA = 25°C
• TTL Input Compatibility: VIH = 2.0V (min.) VIL = 0.8V (max.)
• Output Drive Capability: 10 LSTTL Loads
• Symmetrical Output Impedance: |IOH| = IOL = 4mA (min.)
• Balanced Propagation Delays: tPLH ≈ tPHL
• Pin and Function Compatible with 74LS174

Benefits:

• High-speed data processing due to its low propagation delay.
• Low power consumption making it suitable for battery-powered applications.
• Direct interface with TTL devices due to TTL compatible inputs.
• Driving multiple loads with its strong output drive capability.
• Easy replacement due to pin and function compatibility with 74LS174.

The GD74HCT174’s CMOS technology ensures low power consumption, contributing to energy efficiency. The common clock and clear inputs simplify the control logic for multiple flip-flops. The balanced propagation delays ensure minimal timing skew in high-speed applications. The TTL input compatibility enables direct interfacing with TTL logic levels, facilitating integration into existing systems. The high output drive capability allows the device to drive multiple loads without significant signal degradation. The device is available in various packages, including DIP and SOIC, offering flexibility in PCB design. The synchronous operation ensures that all flip-flops are updated simultaneously, maintaining data integrity. The hex D-type configuration provides ample storage capacity for parallel data processing. The clear input allows for resetting all flip-flops to a known state, facilitating initialization and error recovery.
