74LVTH322374ZKER

74LVTH322374ZKER Description

The 74LVTH322374ZKER is a high-performance quad 8-bit D-type flip-flop from Texas Instruments' 74LVTH series, designed for 3.3V systems. Operating at a 160 MHz clock frequency, it offers low propagation delay (5.3ns @ 3.3V, 50pF) and balanced output drive (12mA sink/source current), making it ideal for high-speed data buffering and signal synchronization. The device features positive-edge triggering and supports 2.7V to 3.6V supply voltage, ensuring compatibility with low-voltage TTL (LVTTL) interfaces. Packaged in a 96-ball BGA (Tape & Reel), it is optimized for surface-mount applications requiring compact, high-density PCB layouts.

74LVTH322374ZKER Features

• High-Speed Operation: 160 MHz clock frequency with 5.3ns propagation delay for rapid data transfer.
• Low Power Consumption: Quiescent current of 380 µA minimizes energy usage in idle states.
• Robust I/O Performance: 12mA output drive ensures strong signal integrity in noisy environments.
• Wide Voltage Range: Operates from 2.7V to 3.6V, compatible with 3.3V LVTTL systems.
