What are the key features of 74ABTH16244DGGRE4?
- 16-bit unidirectional buffer with 3-state outputs and active-low enable for high-speed bus isolation and direction control
- 64 mA output sink current (I(ol)) enabling robust drive of heavily loaded data buses at ABT-family speeds
- 50 pF load capacitance rating in 48-pin TSSOP package with RoHS-compliant Pb-free e4 finish
What is 74ABTH16244DGGRE4 used for?
The 74ABTH16244DGGRE4 is designed for high-speed data bus buffering in memory interface circuits, FPGA I/O expansion, and backplane bus drivers where 16-bit wide unidirectional data paths must be isolated or level-shifted. Its 3-state outputs and enable-low control make it suitable for bus arbitration in multiprocessor systems and industrial computing boards.

Frequently Asked Questions
How many data bits does 74ABTH16244DGGRE4 buffer simultaneously and what is its output current rating?
The 74ABTH16244DGGRE4 buffers 16 data bits simultaneously in a single package. Its output can sink up to 64 mA, allowing it to drive heavily capacitive backplane bus lines at high speeds without signal integrity degradation, even with 50 pF of load capacitance per output.
In which bus direction mode does 74ABTH16244DGGRE4 operate and how is it controlled?
The device operates in unidirectional mode — data flows in one fixed direction from inputs to outputs. It is enabled or disabled via an active-low enable pin, placing all 16 outputs into a high-impedance 3-state condition when deasserted, allowing the bus to be shared with other drivers.
What logic family is 74ABTH16244DGGRE4 from and why does that matter for mixed-voltage bus designs?
It belongs to the ABT (Advanced BiCMOS Technology) family, which offers fast propagation delays and high drive strength compatible with 5 V TTL bus levels. This makes 74ABTH16244DGGRE4 interoperable with older 5 V TTL logic while delivering the speed needed for 50 MHz and above bus operations in workstation and industrial controller designs.
What package does 74ABTH16244DGGRE4 come in and how does it help with 16-bit board layout?
The 74ABTH16244DGGRE4 uses a 48-pin TSSOP (JESD-30 code R-PDSO-G48) package, which places all 16 input and 16 output pins in a narrow, fine-pitch outline. This simplifies PCB routing for parallel data buses by keeping all bus lines on one component rather than requiring multiple smaller-width devices.
