SN74LVTH16244ADGGR 16-bit buffer and line driver ic 3-State Output 48-TSSOP
The SN74LVTH16244ADGGR is a high-performance, 16-bit buffer and line driver integrated circuit from TI, engineered for robust signal buffering and bus driving in mixed 3.3V/5V voltage environments. Belonging to the LVT (Low-Voltage BiCMOS Technology) family, it combines the high-speed switching of bipolar technology with the low power consumption of CMOS, making it ideal for high-speed, high-drive applications in communication and computing systems. This device features non-inverting buffers with 3-state outputs, organized as two independent 8-bit sections, each controlled by a separate output-enable (OE) input. Its primary function is to isolate, amplify, and drive heavy capacitive loads on data buses, memory addresses, and backplanes while providing essential live-insertion (hot-swap) capabilities to prevent bus contention during system maintenance.
This 16-bit buffer operates on a 3.3V supply but features 5V-tolerant I/O pins, allowing seamless interfacing between 3.3V and legacy 5V systems. It delivers a high output drive of up to 64 mA, enabling it to drive heavily loaded or long transmission lines without significant signal degradation. Key specifications include a fast maximum propagation delay of approximately 3.5 ns, supporting high-speed data transfer. The device incorporates integrated bus-hold circuitry on all data inputs, eliminating the need for external pull-up or pull-down resistors to maintain defined logic states.
SN74LVTH16244ADGGR buffer driver Applications
● High-Speed Bus Interface and Buffering: Essential for driving signals across backplanes and between boards in servers, routers, and telecommunications equipment.
● Memory Module and Address Line Driving: Provides strong, clean drive for address and control lines to memory modules (e.g., DIMMs) in computing and embedded systems.
● General-Purpose I/O Port Expansion and Isolation: Isolates and boosts the drive capability of I/O ports from microprocessors, FPGAs, or ASICs to peripheral devices and sensors.
● Live Insertion (Hot-Swap) Support: Used in systems requiring hot-pluggable modules, such as RAID controllers, network cards, and CompactPCI systems, to safely connect and disconnect boards while the main system is powered.
● Industrial Control and PLC Systems: Buffers control and data signals in noisy industrial environments, ensuring signal integrity over longer cable runs within factory automation systems.
