The TC74VHC273FT is an advanced high-speed CMOS octal D-type flip-flop with clear fabricated with silicon gate CMOS technology. It achieves high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. This device contains eight edge-triggered D-type flip-flops with individual D inputs and Q outputs. The common clock (CK) and clear (CLR) inputs control all flip-flops.
Applications:
- Registers
- Shift registers
- Memory storage
- Data buffering
- Control circuits
Features:
- High-speed: fmax = 160 MHz (typ.) at VCC = 5 V
- 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)
- Positive edge-triggered clocking
- Direct clear input
- Wide operating voltage range: VCC = 2 V to 5.5 V
- Pin and function compatible with 74LS273
Benefits:
- Improved system performance due to high-speed operation.
- Reduced power consumption leading to energy efficiency and extended battery life in portable devices.
- Enhanced noise immunity ensures reliable operation in noisy environments.
- Simplified data storage and manipulation in digital systems.
- Easy reset of all flip-flops with the common clear input.
Additional Details:
The TC74VHC273FT is supplied in a TSSOP package. Data at the D inputs is transferred to the Q outputs on the positive-going edge of the clock pulse. A low level on the CLR input resets all Q outputs low, independently of the clock. It operates over a wide temperature range, making it suitable for various environments. The input and output pins are designed to prevent latch-up, further ensuring reliable performance.
